Similar to VRChat, I've found I hate Rec Room. I like the idea, a sandbox featuring user made environments and games, but it's full of children. Lots and lots of children. I hate children.If you want a game that is a lot more sedate, with no time pressure at all, but is still engaging, you might try Hot Dogs, Horseshoes, and Handgrenades
Basically it's more of a realism sandbox. Lots of guns, lots of galleries, all painstakingly made to work as realistically as possible.
And here's an anti-recommendation: Stay away from VRChat. Unless you use it to make a private room to talk to people you already know.
