If you play many RPGs - especially Japanese ones - this will be one of the best things you read this week. It's a painfully exhaustive and accurate list of the genre cliches. I particularly like this one:
Pretty Line Syndrome (or, Crash Bandicoot: The RPG)
Seen in most modern RPGs. The key to completing your quest is to walk forward in a straight line for fifty hours, stopping along the way to look at, kill, and/or have meaningful conversations with various pretty things.
Anyone who's played Final Fantasy X will know what that's all about...
