I'm pretty sure that RUSE was the exception to the rule. Every other recent Ubisoft game has used UbiDRM. Not really sure why they even bother. It took a few weeks to crack at first but now it can be cracked in a day. I don't recall Splinter Cell Conviction, PoP: The Forgotten Sands, Settlers, HAWX2 or Silent Hunter lighting up the sales charts either so I don't think the DRM is really helping their sales.
