If this DRM would actually work and thwart illegal downloading (even delaying the inevitable for a few months) then I'm all for it. But it doesn't. I see some are saying they're OK with this if it's going to prevent it from showing up on torrent sites, but it won't.
The argument goes something like "What's the big deal? I mean who doesn't have high speed internet nowadays?" But that's missing the point. What about customers who just want to be able to use their software the way they want to? Playing a single player game without being connected to the internet doesn't seem all that unreasonable but apparently Ubisoft doesn't think so. What about laptop users and others who aren't able to be connected to the internet all the time?
Look at what EA\Bioware did with Dragon Age and Mass Effect 2. They learned the first time that all the InSecuROM DRM did was cost a lot of money and thoroughly piss off paying customers and passionate fans. I had to download a crack for the first Mass Effect about a month after I bought it because EA said I had reached my limit and were dragging their feet with issuing more activations. There wasn't even a revocation tool for the first year and a half that Mass Effect was out. So while waiting for EA support to get back to me via e-mail I just said screw it. Very sad.
This whole thing is so illogical. However if EA can learn a lesson there is yet hope for UbiSoft. Thankfully Ubi makes crap games for the most part so I won't be missing much by not buying their buggy ass games.
