Alright! Hope to get some great discussion going. This is a great little indie game! Its appearance in the Humble Bundle that it was a part of was a STEAL.
You have to figure out what role you want your ships to have. With that role in mind you design your ship.
Having studied the tactics of Admiral Nelson of the British Royal Navy, I like to design ships with one main purpose: Get in as close as possible and dish it out. To that end I put things like quantum blasters on the ship. Close the distance and get those shields down, then I use multiple beam lasers to get the job done from there. My cruisers are designed to take punishment, and I use a mix of reflective and heavy shields to that end.
I don't have good Frigate builds. They usually die quickly and there's not much you can do about it. My cousin and I have been going back and forth with experimental builds trying to find ones that we like. I like making "missile frigates" so they can sit back behind the cruisers and just fire barrage after barrage of missiles and that seems to do alright.
Fighters are pretty tough to do too. The crew restriction kills. You want to have enough to counter/outlast enemy fighters and possible get some light strafing damage on enemy frigates/cruisers.
The key in the campaign is getting honor, which you use to unlock more modules and ship designs. After you beat a mission, to get any significant honor from the battle you have to use a smaller force than before. Therein lies a very fun challenge.
I like using the main race you start with for the most part. They all have their little perks. Again it's find what you like using and use the race that gets a benefit in that area. Imperials get shield benefits so I like to use them too, but their ships just look so weird!
That's all I got for now. Anyone else who plays, what do you like to do? Hope that gives you some ground to start on Garlick, be sure to share what you're doing too. Chances are you'll give me a few good ideas or we'll help each other produce super unstoppable ships!
