Diddy Kong Racing got great reviews, but we just couldn't get into it after Mario Kart.
MK64 had vastly superior racing and weapons models, DKR's claims to fame were its Mario 64-esque adventure mode and overworld, and the ability to fly. I'd love to see at least the former make its way into Mario Kart, although that'd probably require some actual work on Nintendo's part.
