Both. But if you need to make a choice, I'd say Galaxy, because that's what I own and I loved it. I don't own Mario Kart Wii, plan to though. If you have more than one Wiimote then you could have your friends come over and play with you. Either way you're getting a good game. So remember, Galaxy for Single Player, Mario Kart for multiplayer.
