There are several who have worked on this over the last couple of years. Cosworth (not to be confused with Coshade) who was the original Dev. of the module, there is still alot in there that you would call his. lettucemode did a whole lot of work once Cosworth stepped away from the project. ACG is the latest addition to the team and has added so much to the project, the Battle Calculator being (IMHO) one if the two greatest improvements to the module, the other of course is the card attachment logic which I had the very very basics done when ACG came on board. Then of course there is little ole me. I have been since the beginning focused on the card data and the data entry involved around them. I have added basic bits here and there along the way to the code too.
I have watched several of the games played in this tourney and I have to say I am mighty pleased with the player base online growing as fast as it is and many of the fantastic players! We are all lucky to have players who love the game as much as Schwenkgott, the original playtester for the OCTGN module and inspiration for many many improvements to overall module. He has taken his own time to organize this, referee, record and comment on these matches. A big big hand goes out to him!
The Arcane Duels team of Intangible0 and Coshade who have been making fantastic videos helping all players both Online and IRL. They have taken their personal time and refereed these games, recorded the videos, and the live color commentation has been fantastic and had many great observations of what and why players were doing what they are doing.
Finally we have to thank Arcanus (the man himself Brian) for creating such wonderful games along with the crew of Toxiq and Laddinfance and all of the others involved behind the scenes. Literally we wouldn't be able to do this with out them! Thanks guys!
