That could work. Also, many (most?) of the Total War games.
I feel like if CA invested in a Total Re-engineering effort, and truly modernized both their engine, the core of their real-time combat, and the core of their over map ("4x-lite") into a better realized 4x game. Then they could have one of the greatest strategy games of all time.
With each game it seems like they are buying a new fashion wardrobe, and slapping on the seasonal lipstick. But it could be so much more.
