They should have learned a lesson from Second Life. It was so much graphically better, more sophisticated and immersive even in 2d .
Users had a world where they could build, interact, buy land, make, buy, sell items and art, go to concerts, have virtual sex, attend classes, build a castle , explore, etc, etc. It would have been awesome in 3d.
This was like 20 years ago! Meta had such an opportunity there but instead had half avatars and chat rooms. It sucked.
It got better the further I got into it. It caused unplanned binging more than once.
