This game is awesome. I like RTS Games and have already played Starcraft II, and I also played Sandship: Crafting Factory on the iPhone, and this game basically is a combination of the best aspects of both of these, because you get factory management with lots of tools at your disposal to make your factory more efficient, whilst also getting RTS and Tower-Defense aspects. The campaign introduces you to the game really well, and the soundtrack is simply awesome. Although one thing that is a bit annoying is that the Breach turret on Serpulo is a bit expensive to build and not even that strong, so overall: mine point five out of ten. The Breach makes Serpulo a bit more challenging than Erekir.
