The virtual reality of a good novel

VR gear keeps getting better and cheaper and — eventually — I’m sure I’ll give it a try. I have some concern that I might like this technology too much. Don’t think I’ll ever become addicted to VR games because, well, I’m just not a gamer. But I could see myself strolling the virtual back-streets of some foreign city for hours at a time. That somehow feels like a bad thing. But…

I can spend three or four hours at a whack lost in the pages of a novel, oblivious to the ‘real’ world around me. Is there a difference between these two experiences?
