AI War: Fleet Command - AI War is an entirely unique large-scale RTS with aspects of TBS, tower defense, and grand strategy. It features single or cooperative play with as many as 8 humans against a pair of powerful, intelligent AIs. These AIs are driven by an AI Progress stat that players contribute to through aggressive actions such as taking control of planets and destroying key units, forcing tough decisions regarding which targets are worth capturing or destroying. Human fleets are usually several thousand ships in size or larger, with games often featuring 30,000 units at any given time across galaxies of anywhere from 10 to 120 planets.
Despite this, players retain powerful control over their fleets in a macro-sense, ignoring painful micromanagement present in other games in favor of actual tactics like flanking. Designed by RTS veterans and backed by strong, responsive support on the official forums and elsewhere, AI War is an exciting and refreshing experience.
Gratuitous Space Battles - Gratuitous Space Battles is a unique strategy game where you play the role of supreme commander of a vast fleets of spaceships, battling against AI controlled or player-designed enemy fleets. GSB is not a conventional strategy game, but more of an RTS/Tower Defense hybrid, where you design the ships, position the fleet, issue pre-battle orders and then sit back and watch the explosive galactic mayhem take place. Did you include enough fusion beams on your capital ships? Maybe you should have assigned some fighters to escort those ships in the middle of the fleet? GSB also allows you to challenge other players by uploading your best fleets to serve as their opposition, in a massively single-player galactic smorgasbord of laser-death!
