Triump Card or not, A Pokémon MMO, which would work well
Imo that would mean graphically acceptable, it doesnt need Crysis graphics, but nice and sweet graphics, maybe Cell Shaded/Wind Waker style, would suit Pokémon.
Open world, and I want ALL the Pokémon worlds from Kanto, to Jotho etc etc......
ALL the Pokémon should be in it, from Bulbasaur to....I dont know i havent been up to date with Pokémon anymore....
Some way of chat/interaction since that is going to be hard, but the game pad offers posabilities.
Stable servers....etc you get the point.
With that kind of game, Wii U sells would double.
