A megathread for this sounded interesting.
To start with, here's an interesting romhack: New Super Mario Bros. Origins. Not only do you get as close a presentation as possible to the original Super Mario Bros., but you also get Lost Levels and each level has a lot more secrets!
For a fangame/translation, The 7th Stand User is a pretty interesting game, being not only an adaptation of Stardust Crusaders but also with plenty of easter eggs and things to find. [And a sufficiently insane plot by the sounds of it...]
Hope people post more stuff!
