I don't know, I guess this is a topic for predictions about the game rather than suggestions or hopes for what the game includes.
My predictions: - PM3DS's gameplay, general layout, and difficulty will be most similar to Paper Mario for the N64. - The enemies will be as awesome as they were in The Thousand-Year Door. - Most of the switch and shapeshifting puzzles in the other games will be replaced with touchscreen-based decal puzzles. - There will be eight chapters in the game and at least four of them will look like worlds from NSMB. - This will be the best 3DS game and the second-best game in the Paper Mario series :D
I'm not too in-depth though. Factors like story, characters, partners, abilities etc. could also be mentioned in predictions.
-The Koopa Kids and Bowser Jr. will appear, possibly be bosses -Past partners will make cameos -Mario will get a new attack option(perhaps actually use fire?) -There will be more than 8 chapters, or an pro-game story -There will be 8 partners -Luigi will have a better role. Possibly help you in some way? -There will be another item to collect along with the star pieces and shine sprites(or whatever they will be.) -This will have the best story ever in a paper mario game -Pit of 100 Trials will be replaced with something similar.
-Mr. dragon will be in -The koopa flute will be in -A pilotwings cameo in PM, or a PM reference in pilotwings -42 -I will play it -Mario will not be the main character, instead you will play as a CYAN yoshi (They're the best colour yoshi, you know it) and Mario will be shredded and used in the litter that you sleep in) -There will be a text bubble -There will be a sign. A sign of impending doom -Francis will be in as a waiter - There will be partners. And blood. And partners with blood. And blood with partners -Someone will complain about it -A radically new feature will be in that will be hated by fanboys that don't like change -Someone will ask if this game is compatible with their DS (oh wait....)
