I know this is probably a nightmare for the devs, but I would love to be able to use my own skins.
I remember asking the Wipeout HD team and they explained what a nightmare that would be lol But flight sim fans are pretty hardcore and I'm sure many of us have experience painting the UV maps and keeping file sizes down.
A long shot I know... it's their fault for making it so close to a PC sim! Now we want it all!
