We are
still having issues with that blasted server hosting the files. We are going to move them to something off-site that has a more stable serving of compressed files. If it comes under even moderate load it causes the zip files to get corrupted like it is missing bytes during the send or something similar.
We are aiming to make the UI as compact, yet as understandable, as possible. Our goal is to allow the UI objects to be skinned, but that is still a few versions away.
As for hosting a game, we allowed the port to be settable which should help with most ISP limitations. I know my ISP will not allow certain ranges to be incoming (which is always a pain) and partially prompted the allowed port changing of a hosted game. We hope to have a form of basic FSM AI in place in the next month so that players unable to host or join MP games can have a decent playing experience on their own.
