In my opinion the best C&C is C&C Red Alert 2. I don't care for Tiberium Wars because the future idea is boring and I don't have fun playing. Red Alert 2 had a good storyline and was haed at times, it took me a day to beat one level! A game like that to me which possesses a challenge is a good game.I never felt that in the others.
yeah im goingto agree with Kamacaz. C&C RAII was well thought out, and it had great custom game features. the only thing that could be better is if you could make allies with cpu and have a team battle.
