They're smaller than I thought they'd be.
Anno at just 5m? It has had five games, so guess the first two didn't sell a lot. Although maybe those aren't counted because the franchise wasn't Ubisoft's back then. Anyway, I played countless hours of Anno 1602, it's genius. The second and third were a little mediocre, but the fourth is awesome again. Anno 1404 was a return to form. Haven't played Anno 2070 because the futuristic setting didn't appeal to me, but I hope they'll make a good successor sooner rather than later.
