re: Smoke and Mirrors.
http://www.cracked.com/article_18461_5-creepy-ways-video-games-are-trying-to-get-you-addicted.htmlA lot of things about video games are smoke and mirrors. If you see past that, and can't force yourself to ignore it, things stop being fun.
Also in that if you look at the section about variable rate rewards, that's pretty much why I don't like things like experience points, leveling up skills, or random drops.
