Achievements and trophies are in fact a retarded waste of time. Look at this one. Imagine the kinda asshole you'd have to be to be like "omg bro lets try to get the same number of enemies!!!1"

How about fuck off.

What's even worse are people who get together with other losers to grind for multiplayer achievements in dead games nobody plays -- but not by playing the game as is, oh no no, but by grinding them out.
