@humphreys: I thought that match was pretty darn good. They need more matches like that and give them a lot of time to fill the 3 hours of Raw rather than some of the other junk that populates the show.
@msavo: It will probably be fine, just know that it is very basic before going in and there won't be any expectations like I had before I had originally bought it. It is incredibly faithful to the rules and cards of the real game however, so the actual base game is still fun.
I will be downloading it again on XBLA as it sounds like it will be free since I bought the original. I would say that if you really want to play a Yu-Gi-Oh! game the DS versions are far superior to this version. Decade Duels is a VERY stripped down game with not a whole lot to offer. The game, at least the original Decade Duels also starts you off with a terrible deck and the only option for single player is to play a tournament, which has players with much better decks.
So basically the only options for obtaining new cards is to grind it out as you will gain new cards even while losing, or to pay for digital packs of them.
Oh man would I love to get my hands on this.... I do think he will have a hard time selling this for so much money, worth it or not. As long as it would take I think parting this out would actually make more money than what anyone would buy it all for.
