I figure it's the only 3ds game so tightly woven into the payment system with it's dlc, at least for stuff I've enjoyed, that I feel it's worth it.
Definitely feels of a character to the Warioware games, partly because it's a lot of fast-paced mini games that mostly challenge things like timing and vision, but also because if video games were made by Wario they'd involve haggling with real money.
I presume it's possible to run this stuff on an emulator and not have to deal with the purchasing and just have the mini games, but I feel like something is lost if the stakes don't involve a couple dollars, and I can't imagine seeing this game on the Switch due to how integrated the 3D is into it all.
Anything I don't own that I want to play from now on I expect to pirate, though I might buy the Sonic Boom games because I'm an obsessive weirdo
