I think this is a genuinely good idea. Sure, it sucks that it probably won't have any board gameplay or at least not a full-fledged thing. This sounds like it could very much be Mario Party: Minigame Mode Only. Which puts the phrase "The Minigames are the best part of Mario Party" to the logical extreme. But I think it's a fair saying that people get excited about the Minigames more so then the board gameplay even when it comes to the old Mario parties with the much more liked Board gameplay.
Because some people don't want to spend hours and hours trying to unlock all the minigames. One of the biggest pros of the recent Mario Parties is pretty much all the minigames are available from the start. MP9 and 10's Board Gameplay may be a big deal breaker fro some. But no doubt that what remained pretty good are the minigames that if you ever got MP9 or 10 it's probably more worth it just to play minigame mode as opposed to the party mode.
But bringing back many old favorites. Albeit it's not really going to be a "fan" favorite list as I don't think Nintendo polled anybody on this. It nonetheless is going to have some good choices from each of the games in there. And it will be nice to see the N64 games and the Gamecube ones remade and made more fresh. Though no doubt the biggest shame about this is how they didn't go full fledged HD and make this for the Switch. The 3DS is fine and all, but it would of been even better to bring this to the Switch for full local multiplayer fun for the whole family.
Still, I definitely plan on picking this up. It will be great to be able to play some of the N64 minigames with characters that never got the chance. You can finally play Waluigi or Daisy in games from the first two Mario Parties. Make Rosalina play in some of the older games as well. Or make DK play in Minigames from Mario Parties in which he wasn't playable in (5, 6, 7, 8, and 9). I also wonder of the possibility of in making up for the lack of any kind of board gameplay they might make the roster bigger then any previous Mario Party game. Maybe every character that was ever playable in Mario Party will return as well as a few new choices (Maybe Pauline for a little bit of Odyssey promotion?)
Oh this should also mean some remixed tracks of the older games which will be really cool. The early N64 minigame tracks in particular could really use an update.
BTW this is the list of already revealed minigames through the trailer and/or the website:
Note: The image maker made a mistake and put Look Away in Mario Party 9's section instead of Mario Party 2's
Obviously there's going to be some questionable calls here. The Beat Goes On was one of those games that went way too long and just ended in Draw's most of the time as long as everyone knew what they were doing. Unless something's changed to make that less an issue that's not going to be a popular choice for the 100. And there's at least 2 luck minigames in that list as well. Still this is 65 of the 100 thus far. Who know's what will be the rest of the 35. I have a feeling Bobsled Run will be another.
But yeah, I'm certainly interested in this.
