I mentioned to Cyrano after the show, that there's a way to livestream onto Steam, which would give at least some chance of people visiting Steam's front page to see the stream is up (as one of six samples, with others being accessed to the right), as well as at least some chance of people visiting Steam's TTS page seeing the livestream.
I've tested this before myself (when Aggressors: Ancient Rome came out), but I don't quite recall how to do it.
As I hope comes across in the video, I REAAAAALLLLY like this game system!
An American Civil War campaign would be epic.
