The idea is as follows: I think Starbound should have the ability to build your own vehicles, and I don't mean like a mech customization-like menu that allows you to change the parts and colors. I mean from scratch, like space engineers but 2d. Not just limit it to ground vehicles either, allow people to build spaceships on planets, submarines, mobile bases, and other neat, unique vehicles. Its just a concept that I think would be a tremendous idea to implement. Starbound is a great game, I play it all the time and even nominated it for the game of the year award on steam. I believe allowing players more customization options would make it twelve times more interesting.
And add a station that makes the modules, like wheels or chassis whit circuit board or slick... And other station that ensamble that modules whit your idea... Be great... But I think that is too difficult to develop ..
