Mainline Mario Series
I plan to beat all of these, which is why I also included rereleases that I felt added enough extra content to replay through the games.
32 Games
Has a whole new side mode
USA's Super Mario Bros. 2 [SMB2-u]
Completely different rendition of SM64, many things were changed
Only playing the story mode or any featured levels
Technical exception, only playing featured levels
Japan's Super Mario Bros. 2 [SMB2-j]
I wouldn't consider this different enough for this list but it adds a new character which is good enough to play through the game again
Port of SMB1, SMB2-j, SMB2-u, and SMB3, but the art style and music is different enough to be replayed
This game is part of this series, but it's not the most interesting
Port of SMB3 with a new artstyle and music, plus additional content with the e-Reader (Advance 3: Yoshi's Island was skipped cause it's a little a complicated)
Port of SMW with a new artstyle and music, plus additional content with the e-Reader
Port of SMB2-u with a new artstyle and music, plus additional content with the e-Reader
Port of SMB1 and SMB2-j but has tons of additional content
Even more technical exception, only here for having unique levels
