Pokemon or Animal Crossing for sure. I think Pokemon MMO would sell better, but I honestly feel an Animal Crossing would work better. Either would work well as an MMO

For the options in the poll, I voted Pokemon, but I'd love to see an MMO based on the Wars franchise.

I say Pokemon, but I think there's a strong argument for a Metroid MMO-ish thing.... Ish. Something like what Destiny is doing. Co-op build your own bounty hunter or assassin. As a bounty hunter, you collect bounties by defeating assassins. As an Assasins, you kill either bounty hunters or people in power. The more bounties you collect, the higher your level goes, and the higher level bounties you must collect, and vice versa for assassins. This would all be the multiplayer half of the main single player campaign, though. I think it should be in the third person, though. And there should also be another multiplayer mode that's more standard online, but it's the federation against space pirates, the feds using more mechanical gear while the pirates use more organic weapons. This would all be made to expand apron the single player though, obviously.

But yeah, Pokemon.
