It's you need to think logically first since you are totally illogical for almost every moments.
You want people to stop complaining on the forums which allow us to complain but yet you keep complaining about others; we complain about issues of this game but you complain about other people; you want people shut up and play but yet you cannot shut up yourself even if you can play it. What a logician you are! You think you can run it so it must be people don't know about their OS if they can't? You think this game is not broken even if so many serious issues have been reported? How stupid can you be? Anyway, I can complain all I want as long as it's reasonable and doesn’t violate the rules.You don't get to decide it.
You need to get one thing straight, it's this game causes these issues, not me nor our OS, since even Ubisoft admits FC4 has issues themselves, your "illogical" defense for them is ridiculous and idiotic. I have enough of knowledge about my OS, I'm also using Win7 with decent specs and I also bought FC4 via download but I can't play it until patch 1.4, and I still have mouse control stuttering and key binding issues like many others. I have 130+ games( including other Ubi's games) and they all run well except for FC4, IT IS BROKEN or at least has serious issues, and Ubi need to fix it!
People complain because FC4 has serious issues, and people will keep complaining if Ubi doesn't fix these issues. You don't get to decide it!
