Um, a number of them... But I'm just generally the type who drops games after a while and then picks them back up again later on and off regularly. Like Animal Crossing. You wouldn't believe how many times I've dropped that and restarted like months later. Pokemon sometimes, too (though usually don't restart with these, I did recently start Pokemon Sun).
A more common one that happens with me is MMOs though. I was really enjoying Palia before I got my mac. Then I got my mac and found out it wouldn't work on here... And was just like, "I'll play it when I feel like it even if it means stealing dad's computer for a bit." -- haven't played it pretty much at all since early January when I got used to just using the Mac.
I've also dropped a number of life/farm sims that I just got tired of. For example... Dreamlight Valley just didn't really do anything for me, so I stopped playing it pretty quickly. Sun Haven I drop off and pick back up pretty regularly. It's basically just how I am: I get tired of things for a while, then return to them later.
Only games I can think of that I just dropped completely was Trace Memory. It was a DS game that scared the shit out of me because I had too much in common personally with the heroine. They remade it with its sequel for Switch and gave it the title Another Code: Recollection, named based on the Japanese title rather than the English one I grew up with. I might try it again if I ever get a Switch, now that I'm more able to handle the idea that it's just a bunch of coincidences that freaked me out. (For those curious, it's a point and click adventure/puzzle game.)
