This game is epic. It takes RTS gaming to a whole new level.
Everything from the on-screen layout to the way your units interact with their environment is fully customizable, allowing you to fight wars the way you want.
The 3 factions are original too, although pretty similar to each other.
This game has massive playability both online + offline with wars scalled all the way up to international levels.
One thing that I feel needs special mention is the naval aspects of the game; it is awesome building these massive fleets and watching them engage with oppposing forces.
The graphics are pretty good too. =]
