I really like seeing the breakdown of what percentage of players have done X, Y, or Z compared to me. When achievements were first implemented, it was the first time developers had real data about how people played their games, and it influenced how games would change after that. I don’t think many people are circumventing them via mods percentage-wise, so they’re mostly a good representation of the sample size’s behavior. I rarely go for all of them, averaging about 35% of achievements per game, but I did just 100% Escape from Ever After not long ago, and part of that was getting all of the achievements in it, which was a fun little extra activity to do in a game I really enjoyed.

If you really don’t want that record attached to you, you could prioritize playing games from GOG via offline installer, I suppose.
