I can't do it. It's one of the reasons I never finished Skyrim is I stopped playing it for a few weeks, booted it up again and found myself in Solitude, couldn't remember what the smurf I was doing - looked at my quest log and was like neeeergh, turned it off again. (yet ironically I manage to do this just fine with MMORPGs)

FPS games on the other hand are far more pick-up and continue. But with RPGs once that immersion has been broken for whatever reason I lose interest and find it very hard to continue and usually end up starting over or playing something else entirely. I think the only game I can ever really do it with is Zelda games because you have a very clear objective and not much changes mechanically gameplay wise from A to Z - if there's any sort of sandbox or non-linearness I often end up boring myself on side content or forgetting what strategies I need to use for certain encounters. (Hence how I got burnt out on Skyrim in the first place)

TLDR:

I do it a lot with Bethesda games, which is always fun since I get to re-learn what all my equipment was from my old character and take a new approach to the world since I'm no longer attached to any particular quest chain. Generally RPGs have become games I revisit over time because I just can't sink 60 hours into a title over a few weeks anymore; it's not particularly time efficient, and I don't really want to just get into the world for 20-30 minute chunks and pull myself back out. Sometimes being an adult sucks.
