Considering the horror stories you tell about your own players, that's saying a LOT.
Do I lol? It's always interesting to hear from the outside.
When I think "player horror story" for myself, I really only think of the munchkin who thoroughly traumatized me (across various games lol), that one time I got completely "owned" whilst running Against the Giants in 2E (holy hell did I get schooled), and various players I mostly didn't DM for but did play with from like 1990 to about 2002. Otherwise at worst it's mostly idiocy rather than anything bad (like the guy who insisted the party hand him all potions to go in his backpack so he could manage them, then tried to climb 70' of rope in full plate, refusing to be hoisted up because it was "undignified". I imagine you can guess the outcome of that one).
I guess people remember others or the "played with" category, which I often forget unless specific subjects come up.
Oh and I got a ton of "terrible DM horror stories" also all from about 1990-2002.
I've never really had to deal with unengaged players. The worst time for that was in like 2010 or so when smartphones had come in and everyone was on Facebook, and we were also so young we all had social lives (lol) so everyone was being pinged all the time by various people, but by 2012 people were largely bored annoyed with that and shut that stuff off (except the poor reformed munchkin, who has a very needy and controlling spouse).
