What are you playing?

It's no mess at all. It didn't start as DKR, Diddy came into it much later at Nintendo's request. So only Diddy is in Nintendo's pocket. Banjo and Conker now fall under Microsoft so were removed to avoid license issues. They could have possibly been in the game but it would be bad business, just how releasing a Halo game on the Wii would be.

I mentioned all of those things, though o-O

The problem comes in where Rare used to be second-party, and there hasn't been a real release on what rights were left behind after their acquisition.

Also: Halo Reach was originally going to be on Nintendo DS if my old Nintendo Powers are to be believed.
