I guess Mario Party 9 due to have more fun memories with it than the rest, even though the car mechanic is whatever...
I haven't played enough of Mario Party 8 to have an opinion on it, but from what little I played out of it, I think the game should've supported Game Cube controllers given how iffy the motion controls were in most cases.
Mario Party 10 was a bit of a stepdown from 9 in quality, but its amiibo Party mode more than made up for it, in my opinion. Heck, I even liked the amiibo Party mode more than Super Mario Party on Switch.
Wii Party is an okay Mario Party competitor, but that's really all I can say about it.
Wii Party U is a bit better than Wii Party, but I haven't played enough of it in comparison.
Animal Crossing: amiibo Festival (which isn't on the poll) is...well, it's just bad.
TC2Kevin posted... NintendoLand would be my vote. So many good times at family get togethers with that game.
Ah, Nintendo Land. I lost track of the amount of hours I shoved into Metroid Blast...
