I'm a boardgamer much more than a card gamer, so I have never heard of OCTGN but I am very familiar with Vassal. In fact, Zun Tsu is probably the best option for Mage Wars. But, heck, I don't care as long as I can find a way to play Mage Wars on line.
I spent four hours today trying to get Mage Wars on OCTGN to work , and finally succeeded. It is rough and clunky, but..
I CAN PLAY MAGE WARS ON LINE!
OUTSTANDING!
Pixelgeek - are you ok with me posting this more generally, or are you lukewarm to OCTGN?
