Achievements can take the fun away from a game...But it can be awesome too.
I don't think I would of ever gone for the 7-day Survivor on DR more than once if it wasn't for achievements (still haven't got it)
And it forces me to go back and actually finish Eternal Sonata on 2nd quest for the AP.
But, it can take away some fun from games if thats what you care about. It can be easy to stop.
Back from the dead, I'm afraid.
