Computer games are in a period of stagnation right now (unless your're a flight simmer anyway). There have been no major improvements to game engines or game ideas in a good 4 years now. Just look at all the Q3 and Unreal-based FPS's, how many WW2 games we have now, and all the RPG's look alike. Just wait a few more months for HALF-LIFE 2, and you won't be sick of the same old dribble anymore.
In the meantime, if you have a joystick, go and download the IL-2 demo( http://www.il2sturmovik.com
). I know it's a couple of years old, but if you like it, you can get Forgotten battles, which is the new and improved version.
