Hi,
As I am learning the cards and the game itself, I decided to create a web browser accessible card database based on Octgn's data.
http://agot.gotdns.com/ (yep, it's running on my computer).
Basically I wanted to be able to quickly find cards I saw posted as part of people's decks, and understand the set/Chapter pack that the card is associated with. There are so many chapter packs, and I'm very dense so I couldn't figure out what came from where. Making this database certainly helped me get a grasp on the basics. Currently my database has a few expansions and chapter packs, some cards don't have text information, and some of the newer chapter packs aren't there (per Octgn).
But I stopped working on displaying the cards because "it's good enough for me", so to speak. If I get positive feedback from anyone out there, I will add features to it. For example, it's meant to be used in Firefox and looks bad in IE. If it breaks copyright issues, then it's back to the shadows--my philosophy is 'try it first, apologize later'.
In any case, the app will later have added a deck builder interface, and import export to csv/xml/octgn feature.
So, feedback is appreciated. Thanks!
