Tomorrow Ubisoft will finally release Assassin's Creed Rogue on PC. Who knows why it didn't launch day-and-date with the PlayStation 3 and Xbox 360 versions way back in November. I'm guessing the publisher didn't want it competing directly against Assassin's Creed Unity on the same platform. The trouble is, my colleagues say that it's a good idea to play Rogue before Unity. So why didn't I just fire up one of the last-gen versions?
