I'll do a "Goldilocks playthrough", as I call it. Not simply completionist, but try and complete quests juuuuust the right way, which is usually a mix between fitting a story narrative in my head, and (especially these days) trying to dodge or workaround the sort of bugs that mess up the Goldilocks playthrough like making sure the owlbear doesn't bug itself back to running around the goblin camp after the 3-4 special dialogues that makes it stay in camp. Once in a while, I'll come up with a new "mission" for myself, like trying out ways to make sure that obnoxious half-elf druid in Kagha's cave gets killed by the Shadow Druids, rather than his more reasonable, but low-HP halfling buddy (which I've yet to succeed with, btw). Or do the most spectacularly satisfying thunderwaves, or blows with that wonderful mallet you can get from one of the goblin bosses.
