Dr. Mario Rx Online
A classic reborn, Dr. Mario is now on the Wii care of WiiWare. WiiWare is a somewhat new feature that is essentially new games you download. It’s good for developers as it cuts down on distribution costs and good for players because of convenience and lower cost. At $10 USD the new Dr. Mario is a steal.
The bad news is it only goes up to 2 players which given that the 64 had 4 players is a bit of a disappointment but being able to play against other people online makes up for a lot. In fact, the other person doesn’t even have to by the game to play; you can send a multiplayer-only version to others for free.
