A tiny pet peeve of mine is when someone says that a new game or new edition is the "next step" in the "evolution" of RPGs. That's a line of crap. Games don't randomly mutate over generations. They are (more or less) intelligently designed. Some corporate committee or gang of designers or lone RPG nut directed the development of that game. When you say a game has "evolved" what you're actually doing is buying into some marketing flak or carnival barker's line of baloney that somehow their new product is more fit than others. The next time someone tries that malarkey on you, consider asking what totally random mutations in the product make it a better fit under the current environmental pressures.
