Pretty awesome. I haven't been able to play much—just the tutorial and a round or two of the first campaign. But I really like it. (This is the Medieval one, for those keeping score.) I never got into Supreme Commander because I felt like it took too long to learn the game. Maybe I'll go back. And in Dragon Age, I felt like I wasting a lot of time beating down trash-mobs. What I like about Total War—and strategy games in general—is the sense that all of your actions have consequences. I'll update you guys as I go.
Save your eyes. Take breaks.
