I'd like to see Convoys
I would Love it so that when you build a spaceport it creates a "freighter" that runs automatic routes to find your nearest "processing" world.
I'd love to have it so that you have to build freighters to increase the ammount of resources being brought into a precessing world and so that you have military and civilian kinds of thigns for example:
Freigters and transports are built at spaceports as they are rather civilian ships.
And warships are built at spaceyards because if you think about it why would a planet only be able to build 1 ship at a time?
Anyway it would be GREAT to have convoys play a part in trade as well, like say if I want to transfer 100kt of minerals to player A I'd need to send a freighter to him/her because I always thought it was funny that you'd have miracle trading going on and the like in the middle of a big war.
Freighters would add a whole new level of strategy to the game because I'd love to be able to say "hmmm I'm at war with player C who is between me and Player A maybe I should from my freighters that are trading with player A into convoys!"
Or on the flipside of that I'd love to be able to send a raider squadron to capture freighters or assault convoys and rob resources! muahahahaha!
And I don't think this would be too hard to impliment because something similar was used in Starships Unlimted which is a far less complex peice of programming then SE and done by a far less resourceful group of people.
Maybe something that makes smaller ships useable for example in RTS games small ships are often great to use as escorts because if you sent that Battleship out on it's own it would easily fall to a squadron of destroyers escorting a cruiser....but that's enough detail for that because this has been brought up b4.
