They could perhaps bring us a Tales of the Abyss remake on the PSP.
There used to be this amazing game at Chuck E Cheese and other Arcades a while back in which you are on like this cart where you pump up and down and stuff and chase this guy that has this orb that can instantly take you from places across the world. The name always escapes me but it was like the only thing i would do and waste all my tokens on for it was so good, and it had different endings and such, I only got one of them I believe. But ultimately, i think it was something like Magical Cart Adventure from SEGA or Konami or something.
It would work great as a Wii game.
