hedwards: I bought AC directly from Ubisoft a few years back, and they ended up shuttering their entire store in favor of a new one. They did drop me a note to tell me to download anything that I didn't still have, but it was pretty shitty the way that they changed policy, now if my game installer gets corrupted or lost, I have to either pirate or buy a new copy.
I refuse to purchase from stores like this. Direct2Drive used to have this policy, so I didn't buy anything from them.
These codes, however, are promotion codes I got with hard drive purchases. I don't have as big a resistance to getting something legitimately free. I haven't bought the last few UBI games specifically because of the draconian DRM they have had.
They are starting to loosen up - well, allegedly as a test. I will continue to bide my time, and if they really do change their tune, then I will go ahead and get the UBI games I've been wanting. I have a huge backlog of games, though, so waiting a year or two doesn't really hurt (it also increases the chances I have a better computer to play the games that I can't max out today).
