Mario Party DS preview at Gamespot.

"Nintendo gave us a few minutes with Mario Party DS at its press event a few weeks ago, and now we've gotten our hands on a prerelease version of the game to subject it to further scrutiny. Not that too much scrutiny was really necessary--this is 100 percent, grade-A Mario Party. Anyone who has played the recent console versions should know exactly the sort of minigame/board game action they'll find in the DS game. But that's probably the most impressive thing about this package, from what we've seen so far: Hudson seems to have crammed the full Mario Party experience into the handheld, even if you have only one copy of the game."
