The latest Prince of Persia was released without DRM from Ubisoft at the end of last year. Ubisoft remained fairly sceptical that this would maintain sales as Ars Technica and Torrent Freak state.
Earlier this year Prince of Persia: Epilogue was quietly released for the consoles as downloadable content. Unfortunately Shack News reports that it won't be coming to PC due to 'business reasons'.
Does this mean that Prince of Persia isn't selling well enough on the PC and Ubisoft isn't willing to release it on PC? I hope not, but I can't help but read between the lines when I read this report. Hopefully Ubisoft will release some figures on how well Prince of Persia is doing later this year.
