Just came across this on the rpg.net forums: "This is a free book in .pdf form written by John Kirk. It is about patterns in RPG design--it, mechanics that you see again and again in successful games" http://legendaryquest.netfirms.com/books/Patterns.zip It's CC-licensed (BY/NC/SA). There's more free (probably CC again) games at his site: http://legendaryquest.com/ I haven't read the Patterns document yet (it's 261 pages), but it looks sort of interesting -- Be seeing you, Web: www.glendale.org.uk Sam.
