Yeah, just like Josh Abbott said, this is a completely new title, and it is yet to be named for the 3DS. Everyone thinks all of the games for 3DS are remakes, but that was only OOT, SF64, and Rayman. That's why the 3DS has nowhere to go but up from here!
As long as the classic gameplay from the original title and the Thousand Year Door are in this, I will be happy. Super Paper Mario was a big disappointment for me (although it wasn't necessarily a bad game).
Thank god in this one the battle scene returns, Paper mario is turn-based battles! not platforming!, anyway, this was also another reason why I bought a 3DS, the 1st game on N64 was I think the best though, It was so awesome and the main theme gave shivers of joy down my back, ahhh! the memories! ^^, the 2nd one was awesome too, and the 3rd just sucked, it sucked, the storyline was decent but it is not the paper mario we all know and love.
