Relevant: The original main character of Dinosaur Planet (the N64 game which turned into Starfox Adventures and moved to the the GameCube) was supposed to be none other than ... Sabre.

I still remember seeing the first screenshots of Dinosaur Planet (next to early screenshots of Conker's Bad Fur Day) in an N64 magazine back in the day and thought "this looks like it's going to be the most graphically advanced N64 game, a nice way to end the console generation". Of course that didn't happen. Conker did still come out though.
