Ok, having buyable bases that can be added in with the next version (Or after set ammounts of time, if we finaly can't find any more to add/fix) is an OK idea. In fact, the only real down side I can see would be the time and effort of having to make, remake, and edit of the player bases, and that the controll issue would probobly get complicated.
However, I have to ask a couple of things here... One: How would the trade station work? The only way I could see is an admin comming in every week or so, tallying up the number of trade bases for each faction, and giving each designated bank the apropreate funds. Unless someone want's to do some serious coding for FL, there isn't a way (That I know of) to make it an automatic thing. Two: Battlestations. I don't know if anyone else has noticed this, but the only stations with weapons worth a d*mn are the battleships. Everything else can be laughed at by just about any player with a semi-decent ship. Perhaps if we gave station weapons a boost (It dosn't matter to what... No player will ever be able to mount them anyway), then a battlestation might be feasable. Heck, it would even give pirates (With apropreate reputation, of course) a reason to stay away from stations, planets, and so on, and stick to the fields where the pirates hang out untill they pounce the tradelanes.
By the way, if the battleship stations can have primary turrets (i.e, the Rheinland Battleship stations have those big turrets with the three "Barrels" on them), why can't the PC's? Preferably with the same models.
