Every Game in the Super Mario Franchise
Only games that are excluded are ports that are too similar to past releases (Donkey Kong Country Returns HD, Super Mario All-Stars Limited Edition on Wii, etc.) interchangeable versions (Dr. Mario NES vs Game Boy, Mario is Missing NES vs SNES vs MS-DOS, Mario & Sonic Wii vs DS, etc.) and crossovers that aren't Mario-centric. (Super Smash Bros., NES Remix, etc.) Literally everything else here is fair-game.
