Alex in the future will you be able to manufacture your own ships and weapons to some degree? And if so, is it going to be like an easter egg hunt, where you manufacture limited to the blue prints (which expire) or will you have the ability, in effect, to mass produce weapons and ships permanently once you've "unlocked" them? Personally I would like a system where rare ships and weapons are extremely complicated and require unique parts and blueprints, as well as exotic materials like heavy metals to build, and their blueprints expire. However, I would also like cheapo units that can be mass produced. For example, hounds and talons, if you are a certain level, you can just pump them out with enough metal, supplies computer chips available. Same thing with weapons, I should be able to whip up ten autocannons if I need them. Perhaps cheap units blueprints can make 3-10, while rare unit can only make one. Just some thoughts.
Also if capturing ships is going to be integral to acquiring blueprints, I think capturing needs to be less random. Maybe a skill "boarding actions" that allow you to select which ship to target, the target has a 100% higher chance of showing up as a boarding action. Or maybe the last ship destroyed has a 100% boost to its probability of appearing in the boarding screen (which makes a lot of sense if you think about it, your ships are right on top of it and its life supports have just started failing). You could also make ship mods for your dedicated boarding ship, such as boarding grapnels (preventing escape) anti-personnel boarding drones (kill enemy crew) or emp satchel charges (preventing self destruct).
