Turns out last week I played Wii with my kids. We had great fun with Boom Blox. The combination of a pointing device and a motion sensor is what enables the Jenga-like mini-games. Something impossible on a Switch.
Then I showed my kids the balance board, which is basically older then them and sat unused for a decade. Not a huge success. Personally I never got used to that gameplay. I think it is just dull, maybe because it remains completely static after all.
