I should have guessed it would be Hades, but I'm really surprised to see Octopath up there instead of Slime Rancher, which somehow is way down there even though it feels way more fun. Since when has fun made something seem longer?
In general, without question:
• The Sims (played semi-religiously for almost a decade til the file became too big for my crappy laptop to risk adding any more GB to)
• Skyrim again (starting over just isn't the same once you've hit lvl 81, and I am grieving)
• Disgaea (bought 3 separate times because my sibling kept selling it to buy other things, and then a fourth when I got out on my own. Conservatively, I have beaten that game a minimum of 9 times. Would play again.)
