It's just Dr Mario but with Luigi and it's on the Wii U rather than the NES and it has online multiplayer now. They forgot to do anything particularly inventive in this downloadable game, but it's a little more accessible at least, and it's still fun so whatever. Well, okay, there are a few new modes, but they're pretty forgettable and you'll never play them more than once. It's fine!
Same thing as Dr. Mario but with the "L" shape. Mostly it is cool because it is different than the traditional Dr. Mario games, but doesn't carry as much weight for me. Especially since Miracle Cure added the Luigi mode which makes this game obsolete. There is no need for me to play this one anymore, but that doesn't mean it still isn't kind of cool. I enjoy it as a puzzle game and think that adding a spin to a game which hadn't had a spin in awhile keeps it relevant.
