When we started the X-Wing vs. TIE Fighter project, our goal was to create the first multi-player space combat simulator to be playable over the Internet. There were several major problems that we had to be overcome to accomplish this goal, not the least of which was the Internet itself. I will review the problems we faced, the approach we took, and the results we achieved. I hope the lessons I learned will prove to be valuable to those who read this paper.
