It's just about the same with COH. You need the resources to get more troops/armor and do that takes some planning... you get one set of engineers to begin with (unless you start with high resources in option menu). If you're playing against a human, chances are you will need to plan an assault - rushing in tends to rush your troops right into a bunker with an MG42 or .30 cal....
I got a problem, I'm hooked on Silent Hunter 3 with GWX3.0 Gold, am I complaining? Heck no, this is a great game.
