Nice realtime strategy game, without much research, but with thick techtree. The main difference, however, is that production depends less on accumulated resources than on income rates. Additional files and info can be found here and here. An open source replica with a very similar design is Balanced Annihilation.

Just install and you are done. The Escalation Mod can simply be copied over. Only prerequisite for using it is, that you can set your display resolution to at least 1024×768. If you do not do so, the game will crash the moment you select your commander.
For direct internet games, ports 2300-2400, 47624 (TCP) and 2300-2400 (UDP) must be forwarded. The latest patch is recommended for compatibility reasons. If you enter the IP (or domain name!) of the host, you end up in a lobby showing this particular host's game. In LAN or VPN only unblock the firewall for that particular game and you are good to go. The MPlayer network cannot be used any more.
