No web page would be complete without a links page! Here are a few pages that I find particularly interesting or meaningful.

History
The Medieval Technology Pages: very interesting page detailing the technologies available to the average medieval. Very enlightening.
ORB: The Online Reference Book for Medieval Studies: a great resource for anyone with more than a passing interest in the Middle Ages.

Gaming
Society of Ancients: The place to go if you want to learn more about specific figures in the Ancients and Medievals game genre; includes many images.
The Miniatures Page: Information and links on just about every miniature game company out there! If you're looking for a specific company but can't remember the name, here is the place to go.
FASA Games: Makers of the Battletech game.
Dream Pod-9: Makers of the Heavy Gear Game, one of the best ruleset for anime style giant robot combat!
The Griff Cryer: Come and see what's going on in our current D&D campaign!

Modelling
Track Link: flat out the best resource on the 'net for armor modellers! Recently the webmaster has been upgrading the site so it may not be available, but keep trying! Also includes discussion groups.
Missing Links: Another excellent page dedicated to armor modellers. Also includes discussion groups.
