According to this information:

GRFS on PC is going to use Uplay friends system... serioulsy? NO ONE is using this system. I have 0 friends on Uplay. ZERO. And I have 300 friends on STEAM and 89 on Origin.

PLEASE, if you want this game to have any chance to suceed on PC you have to jump to STEAMworks. Is where ALL PC gamers are. Is where the PC COMMUNITY is.
