Sometimes, I really appreciate achievements, they can make me play a game differently than I normally would. I remember Half Life 2: Episode 1 had an achievement for firing only one bullet throughout an entire playthrough- I enjoyed being "forced" to use the Gravity Gun creatively so much that I do that basically whenever I replay the game now (which is not very frequent anymore, but still).

Also, I've been playing Crosscode recently (which is good, you should all get it ), and some of its achievements seem at first glance to be really poorly designed grindy shit. But the actual numbers are pretty low, and some of them are for actions I basically never did, like guarding. Looking at that achievement made me go "oh shit, I can totally do that if I just try a little bit," and that in turn made me realize that a Defense build was actually very strong, and it made me have a much easier time with some fights I had been struggling with. Plus, as an added thing, achievements are worth points that can be used to make your New Game Plus runs increasingly ridiculous, and that's pretty neat.
