It's available in my Tradewars downloads section. You can try it out alone by following the instructions in the file "ReadMe.TW" included in the download package. To play with other players, you'll need to find or create a server. You can run a part-time server with a basic dial-up connection by running TWServer.exe (also included in the download package) whenever you want people to be able to play the game. For a 24 hour server, you'll need a dedicated connection, or a MUD hosting service. A web search should turn up a few hosting services, and your current ISP should be able to provide a dedicated connection.
At the moment, I'm not aware of any 24 hour servers. If you know about a Tradewars: TNE server that's running full-time and is open to the public, mail me.
This varies randomly from reset to reset. On average, there are about 125000 planets orbiting about 2500 stars.
I don't presently know what causes this, but on some Windows systems there's a problem with blocking connect() calls. It's not the OS, since I've had reports of it on 95, 98, and NT 4, but it doesn't happen on most systems. As a workaround, the 0.09 prerelease includes nonblocking connects. If you have the problem with 0.08, please try 0.09 and let me know what happens. Unfortunately, however, the 0.09 prerelease is not complete enough to be a playable game.
I made the mistaken assumption that when Windows notifies a program that a window has been resized, the new size will consist of positive numbers. A discussion of a related problem in Mozilla/Netscape 6.0 leads me to believe that this occurs when minimizing the window. Subsequent testing has confirmed this. The (annoying) workaround is to never minimize the Tradewars client window. If you experience this assertion under any other circumstances, let me know. The problem is fixed in 0.09.
