This is not a U-turn, all this is, is that Ubi wants to look less rediculous! As Apex said, any hardware changes or for that matter any change at all in a paying customer's inventory is not Ubisoft's business. If I pay for a game, it shouldn't matter how, where and when I'm going to use it. Hell, I have three computers and a laptop in my house I should be able to run it in all those machines without issues. On one hand you are paying money and are still subject to the whims of this spectacularly stupid DRM and on the other hand you can just pirate the game for free and you dont have to worry about any DRM as they get cracked sooner or later anyways, which method would you choose?
Who is the guy who's responsible for these inexplicable decisions in Ubi? lol! Compare this with consoles, no DRM no platform specific checks, I can easily exchange games with friends etc etc, why the hate for PC gamers?
