Here I will (and cell free to contribute) create a list of features I'd like to see in the distant future, potentially even as down the road DLC.
FIRST: a dynamic campaign with campaign level strategic AI. I'm thinking something like Rule the Waves IN SPAAAAACE! Where we basically play the role of the admiralty for one of our space nations and have to make military decisions based off of semi- random political and foreign relations changes.
SECOND: about two more scenario based campaigns, fighting for the other sides perhaps.
THIRD: differentiated faction ship designs. Obviously since we have a designer, we can do what we want, but maybe each faction has certain strengths and weaknesses in production and thus have mass or cost penalties for technologies outside their area of expertise, so their units are designed to take this into account, and players are encouraged to do likewise because of cost concerns.
FOURTH: capacitors that would allow a ship to fire bigger weapons than it could technically power at a lower rate of fire.
FOURTH AND A HALF: keel-mounts to put really flipping huge weapons in a narrow but long fixed mount buried in the hull. With above this would allow for monstrosities like the Halo games' MAC cannons. Effective? Probably not. Fun? Heck yeah!
FIFTH: the ability to separate a laser's internal organs from its aperture. There's no reason the lasing equipment needs to be anywhere near the ball turret. Also, allowing more than one turret per laser to increase effective coverage without significantly increasing mass. (Plus redundancy, yay! ) potential benefit: putting the guts of your laser between two armored fuel tanks and d distributing turrets so that one small nuke can't kill them all.
FIFTH AND A HALF: this one's purely aesthetic, and iknow the core gameplay comes before graphics, which is why this is a far future request, but laser Ball turrets that actually look like the real thing (see airborne laser)
EDIT: autocorrect will probably start world War 3 by complete accident.
