Well, bringing Diablo up works here because those games bore the shit out of me
When I play games they either get every bit of my attention for 3-5 hours or are played on the Switch while watching something (grinding in JRPGs is my mindless release valve...but I need those story beats to keep me interested). Dungeon crawlers can't keep my attention on mechanics alone.
At least part of this is just due to the fact I didn't have a computer capable of running anything more complicated than RollerCoaster Tycoon until I was almost out of high school, so basically any genre with its roots in computer gaming baffles me. Every time I bring up how much I adore RPGs and someone brings up a CRPG my face just goes pale. Oh, right, those are RPGs too. It's weird to think about how separate computer and console gaming used to be.
