i care about them. not enough to go out and buy games purely for achievements, and i wont play a game if i dont find it fun. but in most games, i try to get all the achievements. currently got nearly all the orange box, COD4 and bioshock achievements, but i found getting most of those fun. most people have been complaining about how boring the little rocket man achievement must be, but i had real fun with it. it forces you to play in a different style, as most achievements do, but some do just get annoying. namely your show sucks on COD4. finding every tv in a level and smashing it, which doesnt sound that hard till you factor in the fact you fight your way through a TV STATION full of the things. and especially when you destroy the last tv in the last room and find youve missed one.
sorry for rambling on. that is all
