World in Conflict, Watch Dogs, and Assassin's Creed IV, all free... Again!
I noticed in the Uplay Account Information page, that the claimed games don't have a CD-Keys vs. the Uplay games that I've bought. I don't think the online features work in the free games. At least Black Flag can't get online and is in "Limited Mode" for me no matter what i try, I've even port forwarded the game.
Very strange. Unless its advertised as such ( I didnt see any small text ) it may be worth contacting UbiSoft support. I doubt anyone would complain about features removed from a free game but it is worth asking about.
