It's worth noting for anyone curious: the Quest 2 can't actually interact with or enter the majority of worlds because of technical constraints (they aren't even offered to Quest 2 users unless the author of the world explicitly opts into it and designs their world for it). Most adults are on private, PC-focused servers.

The application is not a stunning technical achievement, but it's unfair to judge the program by jcim's summary, because he seemingly went into it without knowledge of how it worked and wasn't able to access any of the interesting places. It would be like judging Skyrim by an SNES backport.
