Not sure if we're using this as the official 1-2, Switch thread, but I liked it so here goes.
I got the game on Friday and spent time playing it on Sunday with my girlfriend. I genuinely enjoyed this, you guys! The fact that there are 28 games total and that the main mode was a board game style format is what sold me initially. Plus, I really wanted something that took advantage of the HD rumble.
So, there's three modes: one board game (as mentioned), a randomizer (just plays a game a random), and then you can just pick one. We played quite a few of the games both via selection and via the random tool. The Copy Dance game is a lot of fun as you dance and try to copy each other's poses. There's a beach flag game where you run in place and then lift up a "flag" as the joycon vibrates. We had a good time trying to mess each other up while playing games like Zen (where you just hold a yoga pose) and another game where you have to rotate the joycon without shaking to much.
A surprising number of games required only one joycon. Eating Contest was one, but that used the camera, so it made sense. There was another game where you shake a bottle and pass the joycon. If it pops on you, you lose. This has the most potential for a drinking game.
All in all, I think it's a fun collection. The videos are cute and helpful to explain the games. Admittedly, I had trouble with Ball Count, and I wish the games were more consistent on whether or not they used the straps. Taking the straps on and off felt cumbersome. I also appreciated the game telling you the level of activity required for each game.
