Make no mistake about it; this is a massive game.

When you’ve found a game design that works, sometimes it’s better to simply build on that design rather than constantly reinvent it. Such a conservative approach is especially true for puzzle games, as they’re typically infectious enough as is, and they are extremely resistant to staling. Nintendo’s Dr. Mario Online Rx adopts this approach, with essentially the core of Dr. Mario 64—from the various modes of play to the music and all—coupled with some new multiplayer- and online-centric Wii-inspired features. At 1000 Wii Points ($10), it’s sure to entice any fan of the perdurable NES original.
