I'd pay $60 for a fully featured console Warioware game, tbh
Make it as content-packed as Gold with mostly new games and maybe some smaller amount of returning ones, plenty of side games and doodads to grind out. They could reintroduce the motion games from Smooth Moves using the Joycons (but maybe limit those to their own mode, so the rest can still be played in handheld.)
And then add a bunch of new multiplayer modes like the Gamecube game that incorporate all of the new microgames. I think that'd be worth full price for sure.
I also wouldn't be OPPOSED to a lower budget, smaller spinoff experience that went for the Jackbox party game model, but it wouldn't really count as a real new Warioware to me. I don't even think Game and Wario was that misguided of an idea, it may have just needed a healthier platform than the Wii U to make it successful.
