Everyone's Pokémon Ranch
Pokemon Ranch is the second Nintendo Wii Pokémon game and the first Pokémon WiiWare Game. It may not look very impressive but do keep in mind these games need to be around 75MB-100MB or else they'll exceed The Nintendo Wii memory capacity.
Some Pokémon fly, some walk but you can interact with all, You use your Mii to walk around in this polygonal, origami styled world.
