Though the official release is saying that the reason founders Chris and Tim Stamper left Rare was to try new things, the truth behind their departure may be that their latest game(s) (such as Viva Pinata) sold extremely poorly. Since Microsoft bought Rare for $375 Million, five games have been put out: Perfect Dark Zero (X360), Viva Pinata (X360), Kameo (X360), Conker (Xbox), and Grabbed by the Ghoulies (Xbox). Many of these games are merely shadows of what Rare’s games used to be like, and many of them were commercial and/or critical failures. Microsoft is promoting from withing for these now vacant positions as Mark Betteridge and Gregg Mayles will replace Chris and Tim Stamper.
