I'd Like to be able to fly the ship and to be able to use it as like a mobile Hub - something like the Normandy in Mass Effect but on a much smaller scale. How cool would it be to host a meeting / pre-op brief in your own spaceship [i assume since you can buy other models you can furnish your own ship too, at least to some degree]. I liked the space battle in Reach, it was awesome but I what makes it so great is it doesn't overstay it's welcome. Using them every now and then in the story / campaign will be cool. Having an option to be able to dogfight them would be even more awesome - so that the fly-boys can fight it out without stepping on the toes of everything else that will make Destiny awesome.
