how awesome would it be if you could create or modify existing parts (in game). it would go something like: parts you unlocked via tech tree could be changed in size. so you could make a fuel tank larger and it would hold more fuel but weigh more, or increase the size of an engine to give it more thrust, but the efficiency would remain the same so it would burn more fuel quicker. to increase efficiency you would need to get better parts from the tech tree. there would also have to be some sort of limit on how big or small you could make the parts because that could just break the game ps i dont know if this thread already exists but i went back like 30 or so pages and didnt see anything
