Just finished a round of VR boxing against a friend in "Thrill of the Fight 2", in mixed reality. He is in Portugal, i am in Costa Rica.
You join in a virtual ring in your living room, have a voice connection and see his avatar rendered in your living room, ready to fight.
I have not imagined how much fun that is and how well it works, also as a workout. It is pretty exhausting after a few rounds.
If you have a Meta Quest, check this game out, it is super fun with a friend who is far away.
