Almost all of them. I rarely finish a game. For a variety of reasons, all added together. The closer I get to the end, the more I want to put it off if I'm enjoying a game, so I will keep finding more and more nuanced stuff to do instead. A new game comes out and I eventually completely forget one of the 10 games I'm currently actively playing when it temporarily becomes 11, then back down to 10. My friends stop playing a game, but my character relied on them... maybe I'll just start over with a character that can solo. Maybe that game will just go on the pile of "not today, but I'll play it soon", until it's been in the pile so long that there isn't much point anymore.

I should mention I am autistic and likely adhd but I haven't got that diagnosed yet. So while some of this is probably normal behaviours, some of it probably isn't too.
