I'm surprised GFWL is still going, even Microsoft themselves don't seem to be too enthusiastic about it - the GFWL Marketplace program that comes with installations doesn't do much anymore, it just directs you to go to Xbox.com.

Last time I used GFWL with Arkham City it seemed to work okay, but in other games before that I periodically had an issue where it'd get stuck at the login screen taking forever to sign in, forcing me to close the game with task manager. I did eventually find a solution, which was to clear your profile in the Marketplace program, but even after doing that it'd still happen occassionally.

Encrypting saves is unacceptable though.
