Yeh, I give you that the ground is the basic flat we usually see in flightsims against IL2's "3D" landscape, but it's not that bad if you use a highres terrain mod, which makes it look almost photorealistic from high alt. BoB concentrates on flat, but high resolution land whereas IL2 is more of an low res, 3D land. Both have their advantages depending of the altitude you are watching them. Other than that, IMO, the graphics are a notch better than in IL2, same goes for some of the models which have more details to them.
I hope Oleg has learned from IL2, as there's not too much to do to make BoB:SoW the best of the best. AI, sounds, effects. That's three things to change, tho one can take out the sounds off, as IIRC, I heard Oleg will be using the same technic he used for IL2.
Oh well, time will tell how it works out.
