I don't see how a partnership like that would have worked in the '90s.
Cant a man dream though?
Weren't they offered to use the chipset that eventually became the N64?
Their Gamecube games did pretty well. Might have been interested if they got bought by Nintendo instead of making all those Xbombs.
Maybe not bought outright, but something like the deal Nintendo did with DeNa, that they get big stakes in each others companies, and start working together out of mutual interest.
