Xbill, the origional, can be found at http://www.xbill.org
I was planning of making a first person shooter version of Xbill, which for now I am calling BBill. The basic design is you are a character like Tux, The BSD Demon, or Dukey (Java). Each character has a hand-to-hand weapon and a range. Your mission: to stop Gates from installing windows, on the computers by killing him. I will be posting further game design on a website soon, but I want to get the public’s opinion before I use up a ton of my time.
