So here is an example of the problem I was talking about on the Stavelot map. 
The problem affects these two white buildings highlighted here, just off the town square:

 
Here is a close-up. As you can see I have men stacked up right in front of the doors. Neither the front nor the rear doors are functional for these buildings, and it seems the only way in is to go through the inside of the adjacent buildings. Also, this is not the only building type affected by this bug. Some of the really narrow buildings on this exact same block are also affected by this, but for now I'll just point out these.

 
Here are the movement orders I have given. I had two separate teams try to enter the buildings side by side at the same time to illustrate the problem.


 
When I hit the big red button, both teams ignored the doors and then started running off to the right:

 
They circled around the corner, made a U-turn, and then entered the adjacent building at the end of the block.

 
Naturally, this meant that they ran right into the bullets of the Americans across the street.

 
So as you can see, it can be a bit of a game-breaking bug when it ends up like that, especially when playing a long campaign where every casualty you take matters. Luckily I save the game at the beginning of every turn anyway just in case something like this happens. I have multiple other examples and screenshots of this happening to other buildings on this same map as well.

I've been running into this same issue in the Kampfgruppe Peiper campaign in CMFB. In Stavelot there are some very dense areas with narrow streets around the town square where I had this issue. There are obvious doorway textures on the front of some of the buildings, yet these doors apparently don't exist because my squads will ignore them, and instead run around the block to the other side or perhaps go into a building a few doors down and then make their way through from there. 
The buildings affected are in a big row like what Warts 'n' all described, so maybe these are those same Dutch buildings.
I remember running into this issue in CMBN as well, but it's been a very long time and I couldn't tell you what type of building or what mission it was in.

Now part two:
As all that gunfire was going on with the two American half-tracks, two more half-tracks were coming up the road behind them, making four in total. Right when the first firefight was ending, the two new half-tracks opened fire down the road. They didn't even see the Stummel right in front of them, but were instead shooting off to the right side of the road where they saw muzzle flashes from the firefight (where my shot-up HQ teams were).

 
Some of my forward troops had already turned around from infiltrating the city and were rushing back to the sound of shooting behind them. They were about to lay a devastating ambush along the road.


 
Now that the Americans were shooting, my troops along the road suddenly realized what was right in front of them and then opened fire.

 
Seemingly every man in this entire squad threw a grenade, and then a panzerfaust was launched:


 
These guys have no idea what's coming:

 
See if you can count how many grenades are in this picture!

 
The half-tracks go boom. Both remaining half-tracks are completely destroyed with all hands lost inside.


 
After such a shocking few minutes, everything fell quiet for a while. My troops went on without their commander back to their original mission of infiltrating the city, and were eventually victorious. 

Here's one of the more crazy close-range firefights I've ever seen in these games. This post might have spoilers for the Kampfgruppe Peiper campaign for anyone that cares.
I was the Waffen SS attacking into Stavelot in the early morning hours, with the skies overcast and visibility almost at zero. You could walk right up to enemies and not see them even at point blank range. As the battle began and my forward platoons were fanning out toward the city, my company HQ and most of the company's half-tracks were kept back a bit. I thought they were all safe back there, silly me!
Before long, I could hear American vehicles moving down the road out of the city and directly at my positions. I wasn't expecting them to counterattack or just brazenly drive straight out at me so I didn't know what to do at first. The vehicles drove right past my forward troops and none of them saw anything, although I could see the sound contacts coming closer and closer. 
An American half-track packed full of troops suddenly veered off the road, turned right, crossed right in front of a Stummel just meters away, then drove straight at my two HQ teams hidden behind a line of bushes, one of them being the company HQ:

 
The half-track smashed down the fence between the two HQ teams and then kept going, and the GIs in the back got up and opened fire into the backs of my HQ teams, causing two casualties straight away:

 
One of the HQ teams spun around and returned fire:

 
Seconds later, another American half-track appeared out of nowhere, following behind the first:

 
Like a firing squad, the men in the half-track all turned in unison and mercilessly gunned down the entire HQ team. A rifle grenade exploded in the middle of them. My company commander was killed instantly, and at this point my jaw had pretty much hit the floor. One of the first casualties in the battle was my company commander, and he was calling in a bunch of artillery at the time so I had no way to cancel. This was probably the least likely thing I had ever expected to happen - my company commander gunned down in a drive-by shooting at point blank range right at the beginning of the battle. 

 
I would soon get my revenge however. The American half-tracks had drove right into the midst of a column of German half-tracks strung out along the road. They turned and started shooting:

 
The US half-tracks both halted and the men started bailing out under heavy fire:


 
A short but intense firefight ensued, with the Americans shooting and tossing grenades in every direction while under a murderous crossfire.


 
The American dismounts were cut down to the last man, although both of their half-tracks managed to escape and drive off into the darkness. Only the drivers survived. I lost a half-track gunner or two but nothing else.

Stay tuned for part two!

If you ask on this forum you are gonna get some pretty biased answers.  
Like a lot of grognard-style wargames, the CM games can be clunky and buggy at times, and they can be very difficult to get into. They are also challenging, slow-paced and extremely time consuming to play. I can easily spend an hour just issuing orders for a single turn, and one scenario might have dozens of turns. You have to micromanage every one of your units right down to analyzing all of their lines of sight and lines of fire, and sometimes you get a huge number of them. Some scenarios are small and easy to play, but some of them are enormous and daunting. At the beginning of a scenario, I can spend ages coming up with detailed plans and moves for every individual unit, and then once the scenario starts, I can spend even longer slowly having my units sneak around and scout ahead and get into their positions without ever seeing an enemy. With some of the larger scenarios, I can play them for hours without ever seeing any action or a single shot fired.
Some people might find that kind of gameplay very boring, but the games do have an absurd amount of detail, depth, historical accuracy and so on. Once you get into them, you can play them for years, and there really aren't any other games like them out there. They are probably still up there with some of my favorite games of all time, and I still come back to them every now and then years later. 
So whether these games are worth the steep price really depends on what type of game you're looking for. Like some others have said, download the demos. Unlike a lot of games these days, the demos for the CM games are very good and give you hours content for free. Every one of the CM games has a demo and I would suggest downloading all of them. I would suggest watching videos of it too. There are some really great video AARs out there that show off the game.

"I surrender!"
"No, I surrender!"
"No, I surrender!"
"I surrendered first!"
"Nuh uh!"

To me, cover does not really seem to matter that much in the CM games. It matters a bit, but it's more about fire superiority. Squads in good cover will often get blown to bits very quickly if the enemy has fire superiority. A single tank shell hitting a foxhole position or the side of a building is sometimes all it takes to wipe out the squad inside. On the other hand, you can also advance across a gigantic open field against enemies in good cover and still take zero casualties as long as you have fire superiority.
Sometimes I think players get too focused on sticking to cover as much as possible. I see people do it in videos and I often catch myself doing it. I become obsessed with cramming all my troops into what little cover is available and then I end up hurting myself because not all of my troops can form a good firing line from inside the cover. My troops become too constricted when I try to only follow what cover is available. And then it gets even worse when an enemy artillery barrage lands on all my troops bunched up in the cover. If I just move some of the troops out into the open and spread them out a bit more, I can get more angles of fire going against the enemy positions, more firepower can get focused outward, and things get easier. Even troops lying prone on open ground can still be hard to hit, especially at a distance.
Units are also the most vulnerable in CM when they're moving. Stationary troops seem to be harder to hit for some reason. It all depends on the situation of course, but I've had success when crossing open fields not by trying to charge across it as quickly as possible, but by taking it slow, stopping frequently (but not for too long), and shooting at everything in sight. CM seems to be a game less about whatever terrain you're in, and more about firepower and angles of fire. It's about getting more of your guns to bear against the enemy than they can, so that the moment they open fire they will get blasted instantly by overwhelming return fire. You wanna think about terrain not in terms of "how open is this?" but more in terms of "can I get a good shot at them from here?" At least that's how I see it.

"I surrender!"
"No, I surrender!"

Well it took me forever but I finally did it! Finished the whole campaign. That was a pretty epic finale there. I was pretty aggressive and forced a surrender with 37 minutes left to go on the clock.
Here's the final tally for the whole campaign:

 
That's 319 casualties for me plus 19 tanks. Most of those other vehicles were destroyed by aircraft.
Soviets took 1,549 casualties plus 90 tanks, 12 assault guns and a ridiculous number of trucks and jeeps. I shot down a Soviet plane in the final battle, making it 2 planes shot down overall, which was a nice surprise. The Soviet planes did absolutely nothing in the final battle except strafe an empty truck and then immediately get shot down. 
In the final battle I took 125 casualties and 9 tanks lost. Several of those tanks were lost due to a couple of horribly botched flanking maneuvers on my part. Most of the enemy tanks were in a big line across the map. Their tank line was very strong, but I managed to break through on the far left and right flanks, so I tried to slip a couple tank platoons deep around into the enemy rear areas to encircle them, flank the rest of their tanks and roll up the enemy line. Turns out the map designer placed some assault guns hidden deep in the rear in a second line right up against the map edge to prevent just such a thing. Whoops! 
The enemy took 467 casualties in the final battle, 23 of them POWs. Plus 18 tanks lost and 7 assault guns. The artillery you get is pretty devastating. One of my observers alone caused 88 casualties, and I didn't even use all that much artillery. I was playing on the highest difficulty so the call times were pretty long. I had the enemy surrounded toward the end, and I was getting ready to dump all the rest of my artillery onto the final enemy positions in the center of their line. I had 150mm shells falling into the middle of a bunch of their positions and I was attacking from every direction when they finally surrendered.
Based on this campaign, if I were to criticize my own playstyle, I would have a few points:
a) I should be more cautious. I tend to start each scenario very cautiously, sneaking everyone around and doing careful recon and doing very well overall in the initial phases, but once the battle is halfway through or so, I start getting more and more impatient and I get aggressive and start throwing everyone into the meat grinder. It's especially hard to be cautious in a campaign like this, where the scenarios are so massive.
b) I should use more smoke. I always forget that I even have smoke, and I'm not very good at using it even when I remember that I have it.
c) I should be more liberal with my ammo and artillery usage. Even though you have to conserve ammo in this campaign, it was never a problem for me at all and I always had a ton left over. Your infantry gets thousands of rounds of extra ammo in their trucks and half-tracks and they can always go back for more. I always have a lot of artillery left over as well. There was a huge amount left over in the final battle. It just takes so long to first find the enemy, then get observers into good positions and then it takes even longer to wait for them to call it in. I get impatient and then I just attack anyway. The artillery is often very effective though when I do end up using it. One of the highlights of the final battle for me was when a T-34 got hit by 120mm mortars twice in almost the exact same spot. The two shell holes were only inches apart from each other. I had only intended to force the T-34 commander to button up, not expecting any of the mortars to actually hit, but I ended up blowing up the tank twice over.
