For normal games I like both,
But for Adult games I like nonlinear cause i'm just wondering "Hmm could I fuck her, or maybe her" and I like to find out the way to do so
I prefer a non linear story but tbh a lot of games are just linear stories with 2 ending that are just slightly different I like the freedom a non linear story gives you a good example of this would be bulders gate 3 but then a good crafted linear game is definitely worth playing
