You only found this out... recently?? I'm not a big achievement hunter, but I am more likely to get a game on a platform that has achievements. I blame the fact that my parents only ever pointed out what I did wrong and "well you should be doing it like that" whenever I did something right for my constant need to get little shiny badges for doing things! I do appreciate well thought out achievements though. Some are clearly just there to try and get you to play more of a game that's a bit lacking. Whereas some games I want to keep playing but I've done everything in-game, so then I'll go through the achievements.
