Empire: Total War is a lot of fun. It feel a LOT like Civ, but I suppose that's both a good and bad thing, and when it gets slightly obnoxious you get to command troops on the ground level and it makes it more fun. It can be buggy, though, and I constantly have to watch the pathing it's doing (YES PLS MOVE THAT SHIP PAST THE PIRATE ISLAND AGAIN). And it has long campaigns, for the actual time period it covers. Although, including China wouldn't have been *that* difficult.
