Until now the system required a constant internet connection or gameplay stopped. Two of their titles now only check for the internet at launch.
Assassin's Creed 2 and Splinter Cell: Conviction are both confirmed as using this new 'lighter version' of the PC DRM, whereas others such as The Settlers 7 continue to require a constant and uninterrupted online connection in order to play.
When the system was first announced by Ubi it caused no end of backlash from the PC community for 'punishing legitimate consumers' and the publisher seemed unmoved that a large portion of gamers wouldn't be able to play their titles.
The biggest issue has been over singleplayer games like Assassin's Creed 2 demanding an internet connection despite having no use for it past the DRM. Now at least Ubisoft is willing to scale back their creation to something far more reasonable.
Hopefully more of their PC titles will start to follow suit. Has the PC DRM that Ubi introduced put you off from buying one of their latest releases, videogamer?
