The Vault wiki has launched a Bethesda and Wikia-sponsored contest in which you can win copies of Fallout 3 and some swag:
The goal of the contest is to make it from Vault 13 (the starting location in Fallout) to Vault 101 (the starting location in Fallout 3) in seven clicks or less. Simply navigate from the Vault 13 article to the Vault 101 one by clicking on article links within the wiki's articles about the Fallout world and games.
On your way to Vault 101, you also need to visit at least one location from each Fallout game (Fallout, Fallout 2, Fallout 3),
not counting Vault 13 and Vault 101. Other articles on your route do
not have to be locations, but you can only use each article once. Every
location that appears in more than one game counts for only one of
them. Categories, templates and other special pages don't count.
