I disagree with this. The most successful applications that I am aware of are in realms where reality is being reproduced and not escaped. The key advantage is that variables in those worlds can be changed and/or stuff isn't as dangerous while still being realistic.

While escapist and fantasy worlds are fun and very much thinkable (and the line is pretty blurry if you think of the use of VR in therapy for example) reproducing reality is very much "a thing".

Domains that come to mind are: medical training specifically surgery and training for miners.
