Gameplay wise it would be interesting was Wario could take powers from enemies by interacting with them and potentially in a puzzle manner to defeat bosses. I'd like to see this just so Wario can be more expressed as a special genre that everyone who likes platformers would get into Wario. The reason why gamers wouldn't want to do this is because there is no multiplayer... Perhaps that's something Wario should work on similar to KIU. Have a treasure hunt in different maps and use "Powers" to get an advantage. I think that would make a quality game.
