Unfortunately ChristopherAZ Nobody else has attempted to do what Meta did with Worlds idea. So you won't find the experience anywhere else in VR. It's very unfortunate but they decided to concentrate on the headset being a games platform rather than a social interaction device. It's a pity but was always going to happen in order to concentrate on gaming. At least there is mobile at the moment, though many are saying it's not a great experience. Honestly, I don't think mobile Worlds will be around for very long either. It's not nice for people who are invested in it, but it's all about financial viability I suppose. Very disappointing but life goes on.
Have you ever heard of VRChat??? it's way bigger than horizon worlds has has millions of players and thousands of beautiful worlds with active players everyday!
