Well I kind of missed this one when it was released, but for those of you who are following this the PitBoss released was released publicly.
Its still somewhat buggy (as a good beta should be) and not quite yet ready for playing a big game imho but worth having a look at none the less.
My one big grip is that its a windows only, although hopefully it'll run ok in WINE.
You can read more about it on the original postingon the civfantics forum
