Fair enough - semantics. Some people have fun doing this, some don’t. You seem to be part of the second group, no problem with that.
Your initial question was „how do people play those games?“ and „being part of the games online community and/or using the communities resources to play the game“ is one answer. ¯_(ツ)_/¯
I am currently into Monster Hunter Rise. It does not exactly do the best job of explaining ingame what „30% Affinity“ on a weapon means. So I looked it up. That was fun to me.
In the end I guess it’s your imperative to research games before you buy them. If they don’t fit your play style, don’t buy them. You don’t mean to say that no one should enjoy „complex“ games, are you?!?
Beat Saber & VTOL VR are my recommendations for VR games that can be more then a 30min ExpErIEncE.
You didn’t ask, I know… :-)
