I agree on the achievements, I never really saw the point to them.  If you look back at some of the older stuff that was impressive in games, often times it was stuff you were not intended to do. Such as getting to a hard to reach area, or killing an enemy in an unconventional manner, etc...  Now it seems like they are there for the purpose of being there; and go from one difficulty extreme to the other. (And for banning cheating in singleplayer; thanks Blizzard!)
