After just a little bit I'm really enjoying this game. They have made what I think is the best way this type of game could have been made. You are the commander of a fleet that consists of a mother ship and plenty of units that you build. Everything moves in 3D space in a way that's quite simple to manuever. Then, your dudes attack in ways that make sense while keeping general formation.
Formations seem to be quite important to the combat of the game.
The graphics and the interface of the game are quite genius. You really need a good interface to pull off a game like this, and I really dig it. The movement disc stuff is great once you get used to it, as is the sensor mode. You need to play the tutorial to move around though. It's easy and great, but it's not something you'll just guess really quickly.
