I actually didn't realize that Peach's castle had a not Bowser version till today. That's all I got a good 5 or 6 times in a row. Distant planet changes are excellent. I love being able to play N64 Hyrule Castle again.
My fav is lavaville and Mario bros. also peach's castle.
I don't actually like distant planet because that creature on the right really steals the camera and forces you over their.
Also, dialga's spear pillar, the hazard one, shouldn't get the cave back. That stage was more hectic without it. Is there anyway to get dialga's to fire that sideways beam on the top layer? That would be better!
Though it never came around, I still want a stage with ridiculously high sides and a top - I'm talking fully charged Fox usmash at 120% doesn't KO (with some degree of DI) and Falcon Punch is livable at around 100% from the center.
But again, I want Norfair and Peach's Castle back the most - they were my favorite non-neutral stages, and maybe even beat some of them out (but I love my FD, BF, SV, Lylat, Yoshi's Brawl) and I was very sad to see them go.
