Ubisoft have an army of leading franchises at their disposal, but the creme de la creme of IPs is the limbless Rayman.
The franchise takes the top spot with 29 Million copies sold. The spin-off colection, Raving Rabbids has seen five games in total for various platforms, including Wii, DS, home and mobile, with the hordes of manic rabbits bringing in the goods for Ubisoft. That said, it's uncertain whether the figure includes the Rayman franchise as a whole, or just the Rabbids portion alone.
Fellow contenders to the Ubisoft crown is the casual Imagine label, followed closely by Assassin's Creed and Prince of Persia.
