If any of you have played Paper Mario: TTYD, chapter 6 was EPIK. The Excess Express is REALLY fun.
But... They cut it off after Super Paper Mario.
I was thinking there could be an app where you could walk arount the trainn in 3D, talk to passengers, or something. Maybe even remixes of the music, too.
Just at leasr SOMETHING that includes The Excess Express. So, ya, brainstorming is allowed!
