Achievements and trophies. Trophies and achievements. They're essentially the same thing -- a little pat on the back for doing something in a game. In some cases, the reward is for something you would have done anyway. In others, you're coerced to play more of a game and/or play it in a different way just to get some meaningless points or symbols. Don't get me wrong, I love these things. I want them. (Even if I don't know why.) What I find curious is that some gamers greatly prefer one over the other.
