I agree tbh, world just felt like a retread of 3 and was the first main Mario game I was lukewarm about. I also really did not like Mario Kart which was the first game with Mario in I had played I actually disliked later M64 killed it for me for years (still the only main Mario game I have been unable to play because I find it so bad). Galaxy 1 (less said about 2 the better) however was phenomenal best 3d platformer ever imo.Ezekiel said:The open levels made for lame Yoshi and going in circles in the Forest of Illusion (I couldn't remember how I got out of there the first time.) keep Mario World from being a great Mario game, imo. The game wasn't that amazing after everything SMB3 introduced and how creative many of the levels were in that game.
So for me the best mainline Mario game would be SMB3 for 2D and Galaxy 1 for 3D. I find it very hard to choose between them but if I had to pick one I would go with Galaxy by the smallest of margins ofc tomorrow I may feel different as its so close for me.
