I remember when GFWL totally wiped my save file of SF4 when I reinstalled it after a few months of not playing. If I hadn't made a backup of the necessary files, I would've lost everything.
The same thing happened with GTA4. Lost all my saves.
Then there was that one time when it just wouldn't let me log the fuck in. And you can't save or play online without being logged in.
There's also the "GFWL update loop", which drives people mad. Google it if you're interested.
tl;dr, fuck GFWL.![]()
