The King of Fighters
Perspectivewise, it's similar to sackboy, but this is much better than sackboy.
I wouldn't say "Much" better, but it is the predecessor and I wouldn't outright say that Sackboy definitively upgraded the formula, albeit it didn't full copy it either. I'd say Sackboy is like 8.5-8.75 and 3D World is like a 10. Better for sure, but not like one is classic and one is trash. There's a few ideas I think Sackboy does that I'm surprised Mario didn't, but most aren't related to gameplay.
