Walkabout Mini Golf is my favorite VR game but mostly because we play it multiplayer as a weekly social event. Really fun though and the courses have really gotten better over time with the DLC. Clash of Cooks, Loco Dojo, Catan, and Cook Out fit the MP mold too, though you’d need a second Quest (which I highly recommend too, if they really get into it).
If you or your girls like puzzles, the ‘I Expect You to Die’ games (1 and 2) are excellent. Basically a spoof on James Bond, where you’re placed in a scenario and have to escape (stationary, you can sit or stand). The Room is also great for that, though it’s a bit more serious. It has some violence but more cartoony stuff.
Rhythm game-wise, either Beat Saber or Pistol Whip are great. Pistol Whip obviously involves guns and shooting though.
Moss and Moss 2 are fun 3rd person games where you control a mouse protagonist. Really neat to see the VR effect with a platform type game.
My girls like Job & Vacation Simulator as a fun toybox to kind of play around in. Cosmonious High is by the same maker and is supposed to be fun in the same vein. Startenders is another one in the genre but you’re working as a space bartender while you uncover some sort of conspiracy. Raccoon Lagoon is a fun little Animal Crossing type game that fits in here too.
Real VR Fishing is one of the better looking VR games & it’s a nice peaceful relaxing take on the genre.
Demeo is an excellent tabletop board game that I think has pass-the-quest gameplay for local MP.
For action RPG type stuff, Until You Fall is a great 1st person melee roguelike. Or In Death: Unchained but might not be better for you instead of them.
Traffic Jams was a fun cartoony game where you work as a traffic cop, sort of.
For shooters, Swarm is a heck of a lot of fun and somehow doesn’t cause motion sickness. Like Spider-man crossed with a bullet hell (more of a heck here) shooter.
Vermillion is a neat painting tool which lets you basically create digital paintings like you would on a regular canvas.
