And as soon as i know from RockPaperShotgun, Ubi has removed DRM from AC2 and SC Conviction with latest patch, so go for it :D
Not removed, just scaled back. You have to authenticate each time you boot the games. They've updated the article since.
Yeah. Basically just the Steam model with a much more minimalistic client.
Although, is there word on whether or not there is still any streaming content?
