Assemblers and refineries come with customizable modules that you can add to increase proficiency, power efficiency, or speed. I do believe that there is mods somewhere on the workshop for thruster modules and gyroscope modules. Personally I would like to see this concept improved and continued. Instead of just a overall upgrade to an item I would wish for different options and selections to allow for more of an engineering aspect.
I would cite from the depths. I would like to see the selection and weapons, industry, propulsion, you name it the more the better. If you want to call a game engineers you should put some actual engineering into it.
