When / why / how did it change from "kill all 5 of a type" to "kill 4 of a type" to win?
An older version of the rules at http://web.archive.org/web/20060818091717/filebox.vt.edu/users/akopczen/Ice-PDFs/Extinction.pdf says to kill all 5 of a type. The current version here says kill 4 of a type. Did Liam Bryan change it, or agree about the change, or what is the history of that? Goulo 09:36, 30 September 2012 (UTC)
- It was an official rules change in 2000 or 2001. You can see the "4 of" rule on the designer's old site (http://web.archive.org/web/20030717171954/http://www.the-radix.com/001C.php). I'll update the link on the main page to the more "recent" version of the rules. - brilk 11:31, 30 September 2012 (UTC)
