Hey,
Nice walk-through - it looks great!
The battle at the end was nice, however, after playing Homeworld and Homeworld II, the explosions in this game aren't as gratifying. Now, the explosion I saw was of a smaller ship, but the thing I loved about Homeworld was stuff getting blown up all over the place - these huge explosions would light up my entire screen and shake the camera - a much more immersive experience and very gratifying, or nerve-wracking depending on whether you're winning or losing

The explosion in this video, a minuscule, shrinking, star of light type thing - confused me into thinking the ship escaped through a portal, no flash or debris - not gratifying at all. Other than that, I'm looking forward to playing this one.
