Fun when it works, but having to deal with a multiplayer game based around hour-long sessions per level where everyone is tethered in with a fickle wire to a limited battery handheld, and not having any auto or quicksave option when someone in the party inevitably disconnects/runs out of battery (a problem that Mario Party had already dealt with 5 times over at this point) but instead forcing everyone back to the title screen to redo said hour-long level over again, is surprisingly not fun!
