Paper Mario Sticker Star. Wanted that since last year before all the New Super Mario Bros. games where announced. But I want those almost as equally as the aforementioned and the same goes for Luigi's Mansion Dark Moon. Paper Mario is ahead by just a hair.
1. Paper Mario: Sticker Star
2. Luigi's Mansion: Dark Moon
3. New Super Mario Bros. 2
4. New Super Mario Bros. U
I absolutely love the Paper Mario series and this one looks like it's going to be a good game!
As for Luigi's Mansion, I played the original one on the GameCube when I was younger, so I can't wait to play this one!
And for both New Super Mario Bros, I like 2D Mario platformers, but they're not my favorite games from the Mario franchise. Here would be my top 5 favorite "kinds of Mario games":
1. 3D platformer
2. Paper Mario
3. Mario Kart
4. 2D platformer
5. Other spin-offs
Paper Mario was one of the things that convinced me to buy the 3DS. NSMBU is a solid-looking game, but not impressive like Mario Galaxy was for selling the console.
