I did some beta testing for Milo (It's John DeCamillo, by the way) for the original Starshatter, and was given Starshatter: The Gathering Storm as a gift this year from my wife. While I haven't had much time to play it, my experience with it has been great and I highly recommend it.
The Gathering Storm does a good job of adding things to the original that I wanted: voice acting, a more fleshed-out plot with cut-scenes (which should make Major Striker happy), better graphics, etc.
The gameplay is very compelling. Absolutely everything in the various campaigns actually acts itself out. If you are on a patrol mission while other forces carry out a strike on an enemy destroyer squadron, the other forces will actually be out there in the background, and you will be able to seem them duking it out at long distance. If you really want to, you can even add a nav point and sail out there to help out with the strike, if you have a loadout that can damage capital ships.
Friendly and enemy forces in the system are presistent, although at times reinforcements will arrive. If your intelligence tells you there is an enemy carrier with 80 fighters in the region, then there will actually be 80 enemy fighters that are sent out on various sorties. Until you and your forces whittle them down, they will be a major threat to friendly forces and relief convoys. If you fly strike missions before establishing space superiority, you will encounter a lot of fighter resistence. If you first engage in a lot of patrols, you can wipe the fighters out and go after the capital ships without having to watch your back.
Both fighter and capital ship combat are very well done, with a lot of opportunity to use various tactics. You can order a wingman to "bracket a target" with you, sending your wingman/wingmen off to approach the target from various angles, thus drawing its fire in two different directions.
One of the things that I enjoy is that as you earn higher ranks, you can assume command of more and more forces, and then even go back and play the whole game. So, you could start out the first campaign by taking command of a destroyer squadron and taking out a minefiled in one mission, then switch over to being a fighter pilot and flying patrols to take out space based fighters and planetary installations. If you want, you can then take command of the carrier and orchestrate the movements of all of your forces, or take the helm of a cruiser for some heavy firefights. Once again, the amount of different tactics and approaches you can use is enormous, giving Starshatter: The Gathering Storm a huge amount of replayability.
By the way, it will indeed be availble in the USA, and is in fact available now for digital download purchase at the Matrix Games website. You can purchase it here:

(And no, I don't get anything for promoting it.
I think it's a great game and I think many of you will really enjoy it).
