Visible cockpit!
I was thinking more like Wing Commander 3 or Prophecy. Plus-points if it moves around like in Starlancer. Come on, get to work now!
Ejection. Surely the GTVA will have invented space-parachutes by now? A credible retrieval-process, and you could possibly just use one o' them Hygeias or something. The escape-pods don't have to be big or anything. Ha, imagine the missions we could script with that!
DirectX 9 bells and whistles. Badassness.
A measure of motion blur would be nice, if it didn't eat all my resources and then some (Babylon 5: I've Found Her is REALLY nasty with motion blur enabled to my machine, which has no problem running, well, anything - so far). Snazzy, innit?
If the nebula could be made out of some kind of fog instead of these... 'poofs', I bet it would look prrrrrrrrrrrrrrrrrrrrretty. If ships passing through could cause turbulence... *Continues to making completely impossible fog-related suggestions which WOULD without a doubt look awesome*
Someone spoke about perspective some time ago, hinting that ships in FS2 could look even more to scale. Well? What're you waiting for?
Also, I think the asteroids look a little funny... I can't point out anything precise, they just feel... strange. I guess I should just leave that one for Lightspeed. That's all for me for now.
