They took out Pipsy in the DS port? I thought only Conker and Banjo had to go, no?
Also, changing up Tiny Kong like they did is a crime against humanity.
Pipsy was in, maybe he meant they screwed the voice.
Only Conker and Banjo were axed, Tiny and Dixie took their place, Taj and Wizpig became unlockable.
I think Conker and Banjo were axed out of the rest because:
Conker and Banjo = MS
Timber, Taj, and the rest = Rare
Not unheard of for a 1st-party dev to retain some rights outside their owner.
And MS obviously didn't want a Nintendo character (Diddy) to team up with their own (Banjo), also it would've been MS characters in a game published by Nintendo.
Strange though is that Brownie Brown co-developed a MS game (Blue Dragon Plus with feelplus+) on the DS, but I guess BB is like the least Nintendo-associated 1st-party (until now), so they were like "eh, whatever", or they indeed don't give two shits about their JP IP's, OR they gave Gooch complete control, MS just has their name in the copyright so they get free moolah, and won't allow a Nintendo console entry.
