Straight to the point: I am very frustrated with the low time limits of some of the official campaign missions. For example, the marines second mission, where you're given an hour or maybe just over to clear the town and advance to the other side of the map to take all the objectives. Not a chance unless you rush, which will only cause extra casualties. Another example would be the "Decisions, decisions" mission. 30-35 minutes to cross the map and exit. The briefing warns of ATGM's, so the only option to minimize casualties would be infantry out front being overwatched by vehicles, which takes far too long.
Previously not knowing anything about modern tactics, I have been taking it slow and cautious attempting to complete missions with no casualties. There really is no other way if you want realistic allied casualties (none for the most part, I guess). The time constraints force you to take chances with the lives of men the real life commanders would not risk.
Having said that, I am very much enjoying the game. When Shock Force was announced I was one of the dissapointed ones, I wanted a CMx1 with an upgraded engine. Did try the demo, but it ran very slow, so hardly gave it a second thought and continued playing AK and BB on and off. So anyway, I gave the marines demo a try a couple of weeks ago and thoroughly enjoyed it. I was sold and can't wait for the Brits. I haven't even touched wego, real time is far more fun and very manageable with the option to pause.
So well done Battlefront. After all the whining in the forums when SF was announced and released, you have created a game that is leaps and bounds ahead of your older games and any other war game. You definitely have my money for the Brits, Normandy+ modules and whatever comes next (East front please).
