I wonder how much CryEngine 2 costs?
Well the original CryEngine cost a lot more than the Unreal Warfare engine, so you can probably reasonably assume that the latest version costs considerably more than the Unreal 3 engine. I don't see why price is really an issue though, as if you had the money to make a game which did the engine justice you'd have the money to use the engine, and money is not usually a barrier to development anyway. ( For example, the Unreal Engine is often licensed with a relatively small up-front payment if they like the product. )
