CM series: Disappointed in AI


Recommended Posts

The CM series might be good against another person, but I find it really lacking a good AI. It doesn't seem to know how to attack. I bought CM:BB hoping the AI would be improved over the first game but I was burned again :( Since I buy wargames for play against the computer, my CM CDs are coasters. I hope they can improve the AI in future games because I feel the games would be great if it wasn't for this flaw.

I have played 99% of my games vs. the AI. I'm pretty happy with what it has to offer in terms of defence for the most part.

Some sort of basic scripting that could be variable would help out for the attack, though it still beats me when I give it +50% forces often enough.

I have an explanation and a few suggestions:

I agree that there are limitations to the AI, especially when it is supposed to attack. It is very difficult to program AI for strategy games. The games that have the most challenging AI are the ones with the most limiting number of strategic elements for the computer to consider. Take chess for example. Chess AI has made great advances because there are many restrictions on the player: the pieces are always the same and can move only in certain ways, there are only 64 squares to consider, each player alternates one move at a time, the setup is identical at the beginning.

Since the main goal of CM is realistic recreation of historical conditions (units, weather, map types, etc.), the developers have created so many different variables that AI creation is made quite complex. The philosophy behind this approach is to give players maximum flexibility in scenario design and strategic possibilities. But unlike in chess or other simpler games, attempting to code an AI that can deal with these infinite possibilities is practically impossible. We take it for granted that our own brains can filter and deal with this much variable information and develop high level strategy around it. The science of AI needs to advance before it can be addressed better. Personally, I'm impressed with how well the AI does in many situations.

"But some games have more challenging AI than CM!" you cry. In between these two extremes(chess and CM), there are many other strategy games that have decent AI. I submit that any game that has a more challenging AI is by its nature a simpler game in terms of variability of factors compared to CM. (I'm not saying that chess is a "simple" game to play and master, just that the parameters are much more limited than in CM.) CM's goal after all was to introduce as many variables that could be modelling historically. This is one of the reasons it makes such an entertaining game, especially between two humans.

There have been some attempts to make CM more single-player friendly. As my PBEM buddy has gotten busier, I've started doing Biltong's Campaign Rules. It provides an entertaining framework for setting the variables in successive QBs. (There's always a BCR thread open if you want more info.)

Another option is to play some scenarios that others have designed for play against the AI. Naturally many of these put the AI in the defensive position, but they still result in challenging games.

When I'm in a defensive mood, I'll design a scenario with an interesting defensive position and then attempt to assault it myself, giving the AI my own defensive designs. I'm limited to more static defenses, but at least this gives me the opportunity to think both defensively and offensively and gain some variety over normal QBs.

The AI in the CM series may be lacking in some respects but it's still better than the AI in the Close Combat Series ( particularly Battle of the Bulge ) tanks will stop out in the open & just wait, rotating their turrets, to be destroyed. Now that's frustrating.

yes use Franco's rules, i have played three games using these rules and it can be very daunting at first but the feeling of not knowing whats behind the hill can be very nerve racking! plus theres nothing like getting lost in the woods with your troops :D im sticking with these rules from now on, i maybe tempted to load up CMBO again :D but im a mod slut and i dont want to spend half a day d/l all those great mods =/

There was a thread some time ago on QB's vs the AI that were challenging, just because of the time period chosen.

Try Jul 41, AI as high quality armour German attacker, you as low quality Russian Infantry. Variable rarity on

Italians/ Hungarians/ Rumanians defending vs AI Armour or Combined arms Russians in 1942/43 is always a laugh, as you have very little/nothing that can take a KV or T34 from the front, so need to plan for flank shots or close assault. And with rarity on, the odd 75mm or captured 76 ATG is very expensive...
