Uplay is terrible. It stays open after playing the game as well. Its like fuck off im done with you now die. What I hate the most is when you screenshot from steam and the damn uplay overlay thing pops up and ruins the shot!
I bought ACIV and ended up pirating it because I couldn't stand Uplay did the same with GTAIV and almost every Games for windows life game... Is a way to legally have the game and end the fuss of the programm overlays but... You lose the online capabilities (that's a plus for me)
Also apparently I can't download my free copy of Far Cry 3 I got with my graphics card. I redeemed it over a year ago, I went to download it and uplay said I waited too long. !@#$ uplay.
I think we all know where I went after that. Although to be honest I still haven't played it since it never was a game that interested me all that much.
