Rare Replay has brought us a...well, rare look at the game that never was, Project Dream.
Way back in 1995, Rare was working on a game called Project Dream for SNES that featured a little boy, Edson, and his dog Dinger fighting a group of pirates. Very few screenshots and no gameplay were ever seen, because the game was scrapped and redeveloped into Banjo Kazooie on the N64.
If you're interested in the history of games or if you're just a big fan of Banjo, this footage and interview with the team is a really neat look at how he came to be.
