this maybe be unpopular, but after playing 3dworld i'm pretty sure it's my favorite mario of all time. Especially after that epic ending. It fixed the issues i had with past marios (not keeping items past puzzles, the whole point was finding stars), and added co-op. Even going as far to bring back character characteristics from mario 2. Now it goes- 1. mario3dworld, 2.super mario world, 3. super mario 2, 4. super mario 3. 5. Super Mario Bros.
