I'd like to see more 360-playing goodjers on trueachievements.com: a site specifically designed to manage your burgeoning e-peen!
If you care about achievements at all, TA is worth checking out. Basically TA recalculates the point value of your gamerscore based on what percentage of the user community has any given achievement; rare ones become more valuable while super common ones (hit start to play!) retain their original value. There's a bunch of stat-tracking functionality, and the user community is pretty good about providing solutions or hints for achievements you may be having difficulty with. You can waste a lot of time here.
Of course, if you think achievements are useless then you'd probably be right, but nobody wants to hear it.
I will not succumb to the preposterous ideals that a man must suffer through a video game of insufficient entertainment. I vow that, with the courage of my brethren, we shall play no more than 3 levels of Kung Fu Panda, no matter how easily gamerscore be achieved. Let not a F.E.A.R. 2 tempt us into the notion that a man has an obligation to finish that which he hath started, if that which he hath started steals from him the very life essence that makes him man, only to return unto him a small percentage of completion on the Gamers with Jobs True Achievements Leaderboard. So sayeth man, "So be'ith."
I must not hunt achievements.
Achievements are the fun-killer.
Achievements are the little-grinds that bring hobby-obliteration.
I will face my Gamerscore.
I will permit it to pass over me and through me.
And when it has gone past I will turn off achievement notifications.
Where the achievements have gone there will be nothing.
Only the game will remain.
