I can live with the connection needed, it just serves 0 purpose for me and if they fuck up on their end I'm getting screwed. That's my beef with the current DRM from Ubisoft. Hell, just look at Settlers 7, people were/are unable to play that game on plenty of occasions due to Ubisofts servers sucking.
I do love Anno 1404 enough to put up with Ubisoft though, so sadly I'm sorta supporting them.
I'd just play Civ IV, SC2 Beta till Diablo 3, SC2 and Civ V come out.
