Yu-Gi-Oh! Online: DevPro

http://devpro.org/ Care to play Yu-Gi-Oh! again, but don't want to buy the cards you need or pay to play the official version? DevPro is a free downloadable program that keeps up to date with the rules and new cards; creating an account is free and so are the cards. There's unrated and rated duels; including Single Duels, Match Duels (Best of 3) and Tag Duels. My username on it is the same as here; Gudmoore. Feel free to add me if you're going to play.
