Labo isn't so much a new franchise as an experiment. Ring Fit is more or less a spiritual successor to Wii Fit. I'll give you ARMS though. Hopefully we get a sequel soon.
You've moved the goal posts far here. Things being experimental doesn't mean they aren't franchises. And Ring Fit isn't a spiritual successor to Wii Fit, it's a new franchise that's in the same genre as Wii Fit. They have nothing in common besides being fitness games from Nintendo.
