The only major complaint I have about it is the the way the downloadable content works. I seem to have gotten trapped into a situation where the only way I can access my stuff is running the game as an administrator. I mean, logging in as administrator doesn't work, and I actually managed to wipe out two completed games worth of saves on reinstall, when I did it from the administrator account, believing that it would solve the problem. And I didn't have any backups either. When I asked help from support, they linked me to a thread that wasn't.
Got to say, I prefer the way they handle the downloadable content with Mass Effect...
But I liked the Fade too. I wish the shapeshifter magic would have given you the option to approach stuff differently in the "real" world as well, because I never really used it for anything anywhere except the Fade.
