Yes, there are a lot more adults on the PCVR version. Just be aware that finding games for some stuff might be hard to do since there's only around 1-1.3k players at peak times.

It is not. Pavlov Shack is the Quest 2 version and only plays with the Quest 2. But if somebody has a PC and buys the steam version, of course they can still play that.
