According to an article on PC Gamer, it seems that the much maligned DRM system Ubisoft implemented for the PC versions of Assassin’s Creed II and Splinter Cell: Conviction, among other games, might be seeing some improvement.

Until now, the notoriously hated system required that PC players maintain a constant internet connection when playing the games that utilized the DRM system, even when playing single-player. Consequently, gamers – who payed full price for their games – would find their games unplayable if their internet dropped out or if they wanted to play on their laptop somewhere that they didn’t have access to the web.
Well, apparently the DRM has changed a bit and playing these games no longer requires an “always-on” internet connection. It seems that the game only requires a connection at launch, to verify the install, and then can be played offline. It certainly is a step in the right direction, but is it enough?
