There should be categories for each of the Party Mode game modes, Battle Royale, Tag Battle, and Duel Battle. I understand that you'd have to add a sub category for each map, but it'd be a cool thing to add just for fun. Heck, just Battle Royale would be great, with the 5 different maps. Also, the rules would have to force you to use Default, or Custom settings.
This is the only Mario Party game on the site I know of with no Party Mode on it. A 100% run of the game would be really an endurance to do, and to me I think the 100% that would take the less amount of time from the games I've played and know well enough is Mario Party 6, as for me I can get everything much quicker. Maybe a speedrun to complete one whole figures list, like All Boss Figures%, or something like that.
