Basically, that's how we got Yooka-Laylee (and that new game called Tamarin, which I think is a GFG spiritual successor).To be fair, didn't some of the members actually leave Rare? That'd make it harder to recapture the feeling. At that point, a fan might be needed to help get it back to its roots. It's how Sonic got some neat stuff, like Mania. These things do happen. Though it's not remotely common.
DKR would've been neat too, though at least we got the best characters from it, Diddy and Banjo.
I said this in the BK thread, but I don't want the current Rare to make the next Banjo-Kazooie game. I'd rather it be someone like Retro (unlikely as it is) or an indie studio like Gears For Breakfast or Playtonic (ironically enough).
