You can do literally ANYTHING. You just get an addon right in game and you can do what ever with it. You can design your own car if you wanted!

Did you like Terraria? Or have you still not played it? Well Starbound is a space exploration! This is fun, make your own spaceship, and meet new people

This is a game that is definitely fun, better than minecraft(but is 2D), there are more bosses, ores, and fun to be had! A must have for indie lovers.
