I'm just curious as to where my fellow "older" gamers stand on the issue of achievements.
As for myself, they've had my hooks in me since early 2006 and haven't let go since.
I don't chase them simply to inflate my gamerscore. I find that they allow me to get more out of a game that I normally would stop playing. For example, if I complete the campaign on a game but there's an achievement for completing the campaign on a higher difficulty or under a certain period of time, I'll go back and try to earn those as well.
It's probably my OCD tendencies but I love trying to unlock as many as I can.
They also make me wonder what some achievements would be included in games from 35 years ago, but I suppose that's a separate topic.
