Not that this isn’t a good game, but I find that Super Mario World for SNES is pretty much Mario 3 with less cruft and more awesome. Save files, hidden exits, and far fewer encounters with the Hammer Brothers all make Super Mario World a much more enjoyable game.

That said, I plan to find a copy of Super Mario All-Stars for SNES so I can play this game with save files. Being able to go to bed and continue playing the next day really improves the experience.
