Hey all. I just wanted to really quick let you guys know that a new Yu-Gi-Oh! game is due to be released soon on XBLA, titled Yu-Gi-Oh! Millenium Duels. From screenshots, it's implied to feature characters and cards/mechanics from each era of Yu-Gi-Oh! (sans ARC V), as well as co-op play and of course the tag dueling that was present in Decade Duels Plus.
Here's the page for the upcoming game:
Hope to see you all in-game, since I've regrettably not played multiplayer all that much in Decade Duels Plus since its initial 2010 release.
