It will be the best ever RTS game you have never played.
Just go and download it now.
You need to burn it to a CD to play it, but the actual game is freeware from the site below.
311mb, in RAR format, unrar, burn and play!
Works on all Windows formats, even Windows 3.x
Also, someone can set up a server for up to 20+ people to play online at the same time, that is when it gets a bit mad, and that was when people had 56k modems, 20+ people, imagine how good it would be if we all got the game and had an online game with a 3mb/sec server.
