Mario Party DS review at Gamespot.

"To say that Mario Party DS is just a collection of competitive minigames is like saying the Louvre is just a warehouse of paintings. These quick tests of skill aren't the usual sort of generic button-mashers you'd normally find in games of this type. Nintendo and Hudson have come up with a spectacular set of "pick up and play" challenges for this handheld installment of the ongoing franchise. They've also crammed it full of play modes and have lavished it with the sort of cheerful polish you've come to expect from Nintendo-branded games. Best of all, the developers have made it so that you need only a single cartridge to get a party going with as many as four people."
