A:AnswerHi, are you referring to the Quest 2 system? I believe one Q2 can have up to 5 accounts. As long as they're willing to take turns playing (and leave some time for you to play, too :) then one unit works just fine.
A:AnswerThere is a usb 3.0 cable sold separately that will link to steam vr games. You can also wifi airlink but the cable is better for quality and keeps a stable connection.
A:AnswerThe Meta Quest Link Cable (model 301-00311-01) is the official brand cable for the Quest 2, though not the only one. Depending on your store, other brands may be available. For the simple plug and play experience, i recommend trying the official one above first, in spite of its price.
Expect the Quest 2 battery to discharge during use when plugged into a computer. If the battery drops to 20%, consider giving it a break, though i cannot speak from personal experience what exactly will happen. I happened to buy a more complicated Link cable. I did not get a simple plug and play experience. (ノಠ益ಠ)ノ彡┻━┻
A:Answerits not meant for children under 10 years of age according to Meta. They do not consider their headsets "toys".. personally I let my young children use the headset supervised to play fun interactive games like Bogo.
A:AnswerIt works with any PC VR game including Microsoft flight sim.. you will need to connect your headset to a VR ready PC with a link cable or the built in AirLink wireless setup.
A:Answeryou can stream movies on it.. but to watch DVD's you would need to be linked to a computer that has a dvd player and watch on the headset that way.
