I love achievements. I used to be pretty addicted to them actually mainly in high school. I would play a game and get absolutely as many as I could before being done with the game. I'd even play the game a certain way to grab some of the harder ones.
But now having a full time job and such less time, achievements have taken a back seat. Unless its a game I really like, I usually just prefer now to beat them and call it a day.
But that's not to say I don't still go for achievements. Especially if they're very easy. No reason not to have the achievement for watching the credits or making a custom character for example.
