Well... I couldnt think of any EA stategy games without googling it. so Blizzard wins by default for me really.
Plus I never really got into command and conquer. The sims cities are classics but i'm taking your question to be RTS as opposed the strategy genre as a whole.
blizzard of course EA Does make many other than sports but I've never herd of a strategy from them. Wait never mind I've l played there lord of the rings and it was great. Still I favor Blizzard just cuz I know many people who play wow and others from them. But seriously? what are some strategy games from EA.
blizzard of course, i heard there forming with activision to make activisionblizzard but its only publishing games so dialbo 3 and starcraft 2 wont be messed.
Uuh, I've never heard of an EA strategy, but EA pwns Blizzard, 'cause they have Need For Speed. Maybe instead of just Strategy games, the topic should be open to just which one makes the best games?
