Ostegun,
It has been a while since I have used the Tabletop Simulator or Vassal to play BG over the internet, but I will see if I can find the files on my computer. Maybe we can get a game in. Do you have Skype? Because that makes playing online much easier and more pleasant, rather than using the chat windows from either TTS or VASSAL (or Steam for that matter.)
Bohan (aka Zelc) programmed the files so he might have a version more updated than mine, anyhow. It has been a while since I have spoken to Bohan or seen him post on the forum. Unfortunately, despite some people expressing interest in the VASSAL module, other than one game with Mike (aka gull2112) which was on the Tabletop Simulator, I don't think I played online with anyone other than Bohan.
