Party games are a big hit around here. I have every console Mario Party, as well as two of the handheld ones (still need the 3DS ones) and even the e-Reader card game. MP 8 and 9 are our faves, with 7 being a third. I hope the Switch goes back to offering up some strong party games like the Wii did.
While I don't normally go for this sort of thing, I think it'd be neat if they offered a compilation Mario Party game which included all (or most) of the boards from every game, a selection of the best minigames from every game, and all of the characters and features that have been in each one. It would be the ultimate Mario Party, though that also means it would offer too much value for them to make it.
