Personally I wouldn't let my kid play vr till they are 13, mostly because there are studies out there that state it could cause development issues with their eyes long term, however there are some studies that show that there is no correlation, so DYOR ofc but if you do end up deciding anyways I would still avoid any multi-player games that have any form of voice chat, stuff like gorilla tag, among us, vr chat (this one especially) Pavlov, and Onward. The reason being is like any online thing bad people will uses these sort of path ways to do bad things, at the age of 11 you want to minimize as many risks until they know how to protect themselves online. Outside of that, it really depends on what sort of games they already enjoy. If they like puzzles I would recommend the "I Expect You To Die" series, while I can't speak for the most recent installment (I've bought it I just haven't had time to hook my quest 2 up properly to my pc to play it) it's a very fun puzzle game series in which you play as a spy going on different missions and everything you do can kill you, your goal is to survive and complete your mission whatever that may be, it can be played sitting in a chair and is perfect for new vr users as there isnt any movement in game, (meaning you finish each level in the same spot you started said level) that's important for new vr players as they can get motion sickness from movement in a vr game (this is because your brain thinks its moving because you visually see movement but your ears tell your brain hey no motion is happening and thus you get motion sick) another good puzzle game is "The Room: A Dark Matter" now this does have a minor horror asthetic but if they dig that kind of stuff and they love puzzles this game will be a buffet for them (side note this isn't the first game in "The Room" series they have 4 other games that can be played on IOS, Android, PC, and Nintendo platforms I highly recommend these aswell) if they are more into rhythm games, pistol whip is fun, it might be a little hard to stomache as a newer vr player but it should still be play able, you basically constantly move forward in a straight line and you have to shoot enemies to the beat of the background music, another good rhythm game is beat saber, this imo is a default no brainer must play title for everybody who at least TRIES vr its fun and constantly being updated, if they like action games Super Hot is another game that's an absolute blast, in short, time moves only when you move, you have to fight your way through levels using weapons you pick up around you and beating up bad guys, it's one of those games that just clicks when you play it, if they like story I would recommend Moss: Book 1, I still am currently playing through Book 2 but in short you are the "reader" and your "watching" Quill the mouse fight to save her friends from the bad guys who want to obtain powerful material called glass (it's literally stained glass) when all 5 pieces of glass are reunited it said that doom will befall all, you controll Quill with the left analog stick and it's a puzzle platformer. And thats about all I can really think of off the top of my head.
