"In Bowser's Castle, we were planning on having the player complete a number of different mini-games as they went along, but unfortunately we had to cut this because we didn't have time. I'm sure these mini-games would have been very silly and fun, so that was a bit of a shame." - producer Kensuke Tanabe
"If we had, then we would certainly have had to put a lot of effort into making events to really show off their uniqueness." - Co-director Naohiko Aoyama
I'm always amazed with just how much content Nintendo's devs can come up with. While these ideas may not have made the cut, I'm sure they'll be recycled for another Nintendo title down the road.
