Ok, so I've been playing the game for a bit and while there's several things I'd like to see, I think that Solid Rocket Boosters (SRB's) are among the most needed, as they are so important In real life. Currently, all rockets in the game run on liquid fuel, and thus are heavier, controllable, and reliable. SRB's are the dead opposite. So, to make up for this lack of SRB madness, I would like to see a resizable nozzle that burns solid rocket fuel, and of course, a solid rocket fuel option added to the fuel tank (obviously.) Thanks for reading and I hope you take my suggestions into consideration!
