LordCinnamon: Actually, I like achievements if they motivate you to try something weird/crazy/hard you would never try during normal gameplay. For example, in Toki Tori, there is an achievement to fill a certain room with 42 blocks. Well, turns out there is only one way to do that, and 42 is the absolute maximum. This results in a sort of mini game (filling rooms with blocks is not a regular goal in the game) which is fun to solve.
But the statistics achievements are very boring (and lazy).
However, the sort of achievements that are actually fun are relatively hard to come up with, you'd have to know the game quite well. So even if the technical problems were to magically disappear, I still think a satisfying implementation of the system would be unlikely.
Yeah sometimes achievements can be pretty cool like the 1 bullet ravenholm or the gnome one. I have more of a problem with the fact that they are shown to other people and are like delixe said used to boost your e-peen.
