I'd like to see a place at the Academy where you can run a Kobayashi Maru simulation to try out new ships.
Have you ever had the opportunity to purchase a new ship and not had the chance to test it, then shelled out the cash only to find it doesn't really suit you? How about a room at the Academy where you can book a 'test flight' of any ship, regardless of level or availability. You then fly it in a single mission map against an ever increasing number of enemy ships to get a feel for it before you buy it.
It should also include all of the C-Store ships, so you could see how you like them.
The limits are you only get to fly that one simulation map as a single player. It could also be on a timer like an STF.
