as a perfectionist who is also an achievement hunter, I honestly hate achievements because the large majority of games have achievements that are either online/competitive based, and I cant be doing with that, and/or get all of x item, and I feel like I need to do it, so I spend hours doing 1 singular achievement.

It's also ruined my experience with games because I cant just play a game, I instinctively think of getting all the achievements before I've even finished the tutorial.
