Pokémon Campaign is a Flash game set in the Pokémon world, but allows for open-world exploration and real-time combat. Catch and level Pokémon, explore new areas, and take on missions in the all-new Campo Region!
Marill has recently been adjusted to be Water/Fairy now that the full type chart has been revealed. There are no Fairy-Type moves in the game, but Marill now reacts appropriately defensively. Also, Steel-Types like Aron and Magnemite lose their resistances to Ghost and Dark, like they will with the release of X and Y.
I've held off on changing Ralts' type until it is officially revealed that it will become Psychic/Fairy, if it is at all. (I'm betting it won't, but we'll see!)
