The strange thing is, there are achievements that are both good AND bad at the same time. Take Nothing Special on L4D for example-
Good because you finish the finale physically shaking because you've managed to pull off a truly amazing achievement, surviving a whole 5 rounds without taking damage from a single special infected. You've made those reflex shots at just the right time, you've repelled Boomers and no-one got hit, and best of all you made it past the tank without getting injured.
The bad? When you're climbing into the escape vehicle and whilst you're waiting the one and a half seconds for the door to close, the rock that the Tank threw comes into the vehicle.
In all seriousness, I agree with most other people though. Storyline achievements are rubbish. I've just played through GTAIV on PC, I've finished the missions and to be quite frank, I can't be assed to go back and get the achievements. Seriously? Get a cab from one island to another? Bugger off.
That said, the achievement system DOES help newer gamers to get better, in the same way that the stats system on TF2 helps them. "Well done!" it says "You managed to kill x number of players that round". Soon enough, that player is hitting that score regularly, and eventually it's a disappointment that they *only* killed 15 people that round.
Take the Boomer for L4D for example. There is an achievement for hitting all 4 survivors with one vomit. That used to be difficult, but if I don't hit at LEAST 3 of them I haven't done my attack properly.
Wordsmith is currently only missing 3 achievements on L4D; Zombie Genocidest (, What Are You Trying To Prove? and Jumpshot

Mirror's edge - Sweet Goodbye. Fucking awesome
Can't think of any bad at the moment, but there are some
I heard that Mirrors Edge has one called "ITS-A-ME!"
You get it by jumping onto a guard Mario style.
Makes me think of Toadstool looking at faith going
"I'm sorry Faith, but the package is in another castle!"
I still don't get why this isn't an achievement for L4D, "Kill a zombie by jumping on it's head". I once killed a whole horde with one jump because they all tried to climb up the same bit of wall xD
