I think the one thing I don't like, from an aesthetic point of view, about the game is the sound the engines make.
To me they sound like a small electronic motor under strain and not a spacecraft in flight.
Is this moddable I wonder?
Sure, every asset in the game is fully moddable. And almost all of the mechanics as well!
Great, thanks. To be honest I could have answered this myself, I've concentrated on the data folder and not really looked at the assets. Sorry for being lazy :)
