Is this an RTS game like homeworld?
Not really. It looks like an RTS in some screenshots, but the game is much more like a ‘tower defense’ game, in that you are not directly controlling your units, but placing them pre-battle and issuing orders. Imagine tower-defense, but with moving towers that you can design from scratch, in space, with cool laser effects. That is a fair approximation of GSB. You do not have control of individual ships during battle. The battle phase of the game is for visual feedback of how your fleet did. You can speed up and slow down and pause the battle to see what happens in some detail, and there are post-battle statistics showing who shot and killed who.
