Oh that’s really rare for me, since I’m not a person who can generally do “grindy” parts well if the grind extends past what is clearly the main intent of the game (that is, usually the story).
The last game I 100%ed is Pineapple On Pizza. A free 10 minute game, 20 if you go for all achievements. Says a lot about me I suppose. 😅
However, I do sometimes go after rare achievements because the ideas behind them sound intriguing to me. But I can’t be arsed to go for all the other stuff, ingame and external, too. One good example of something I had to do is that the expansion Hate Plus has an achievement that for the longest time would get manually credited by the dev if, at a fitting moment in the story, you bake an actual cake and take a picture with it in front of the monitor at that scene.
Was time to bake something again, anyways. 🎂
