Have Trent's action's have a greater effect on the universe. For instance, i've probably shot down 500 Red Hessian fighters and destroyed at least 25 of their starbases. I'd like to see them respond to this, either sending out Bounty Hunters after me, or their influence in Rhineland becoming weaker due to the massive losses I've inflicted upon them. Perhaps after giving them a serious enough beating, they could even come towards you with an offer of a Non-Aggression Pact, where they pay you to leave them alone, and in return, they go from Hostile to Neutral.
A kill list that lists starbases, capital ships (not just battleships) and lists your kills by faction.
Something that I think would be helpful for new players.
A better explanation of the types of shields and weapons, and who uses what.
For instance, say I'm friendly with the Corsairs, but hostile with the Red Hessians.
I'm thinking about buying a Graviton Vs Molecular shield and some new weapons.
You could either bribe or find out through experience, that when you go to purchase a weapon, it would say "This weapon is tough against X shield & weakest against Y shields. X shields are commonly used by these Factions, A, B, & C, while Y shields are used by C, D, & E."
Same thing for shields.
Tougher enemies based on levels, not just systems. I'm at level 35 and flying a Titan. I hate having to fly all the way from the New York System to Omicron Gamma just to get some worthwhile missions.
More variety in the Job Board missions.
Perhaps be able to open your own starbase. You would get monthly revenue from docking fees, commissions on equipment and commodity sales, and sales from the bar.
You would also have to outfit the starbase with turrents, and perhaps pay a faction for protection. You could also choose whether to make it a safe haven for honest traders, or a pirate hideaway, and perhaps offer Cardamine sales. You could also use your starbase to store extra fighters, or begin your own trading company. You would have to purchase Freighters, outfit them with turrets, and perhaps escort ships, and then send them on their merry AI way, and collect a percentage.
Sometimes, they would have problems with Lane Hackers in certain systems, which would require you to fly out and clear them out personally.
Perhaps be able to order the construction of your own Trade Lanes and Jump Gates, especially in the Uncharted Worlds, which would be nice instead of having to cruise around the Border Worlds at 300 kts all the time.
You would have to purchase the Trade Lane parts, and perhaps protect the crew installing them from attacks by pirates.
A better intimidation and Hail system. I'm constantly harrassed by a handful of Liberty Rogues in Starfliers, while I'm in a Titan with level 10 guns.
Also, be able to ask pilots for directions. Say you just jumped into an Uncharted System. You see a guy flying by, and you can Hail him to ask"Hey, where's the nearest starbase or jump hole?"
Hints to where starbases & jump holes in uncharted systems are. Like, "your sensors pick up a trail of Cruise Engine particles heading towards sector D4."
Improved Cargo Hold. Like, you could have a refrigeratored Cargo Hold that would keep Luxury Food & Alien Organisms from pershing so quickly. Or a Smuggler's Cargo Hold that would block scans by Police. Maybe external cargo pods for carrying extra commodities.
A readout on your ship's total capabilities. For instance "your total guns do a combined Shield Damage of X and a combined Hull damage of Y, with a Power Drain of Z."
Improved Cruise Engines, that would allow you to fly faster. Flying around uncharted systems without trade lanes at 300kts gets rather tedious after awhile.
More alien races, not all of them hostile.
I know a lot of these are probably unworkable, but I thought I'd throw them out for you guys to chew on.
