I seriously don't see the point of Uplay. It's just basic unlockables, bu for some reason you need to register online and go through a points system to unlock them. Plus it looks like there's going there's going to be more content available than there is points awarded in the end, which is annoying.
I guess it's a softer way of fighting piracy or something, but it still sucks.
