Dark Souls had me hooked almost immediately.
I put 50 hours into Skyrim my first time playing, and then stopped and never picked it up again. I just never felt like picking up where I left off.
I grew up on Metroid and MechWarrior 4, and they remain some of my favorites to this day.
All in all, I find myself playing games that are easy to pick back up after being away a while. Lots of stuff on Switch for example, Pokemon, Stardew Valley, etc.
