It's about extending the life of a game, to me.
When I've finished a game, if I've really liked it, then it gives me an incentive to go back and play it again.
If I've not really liked the game then I couldn't care less about them.
To be honest, it's not until I've finished a game and decided on whether I've liked it enough to play it again that I even look at the achievements. And even then the score doesn't bother me, just the task it wants me to do.
Heck, I even drove round san andreas for hours making jumps just to get a number closer to 100%. I didn't even get points to show off for it back then.
