Honestly? If we'd known that there was going to be fighting in orbit and on the moon I'd have probably wanted to design a space rifle or something, because a machine pistol that promotes rate of fire over accuracy is a horrible weapon in Zero-G and the Moon. All that kickback is bad enough under Earth's gravity...
Not to mention, with space being space, that the gun would fail to cool down and might start melting after a few bursts.
You're not exactly mining stuff from empty space in LEO either. No, the resources represent gains you make on Earth as a result of your control of space. Don't ask me why owning the Moon gets you more ore, it just does.
Fair enough.
Simple answer, Big rocket intimidates small countries.
So lets keep everything how it is and have tech adjusted and listed to reflect that.
It would be unfair to go from balanced to losing horribly because of gm messup and retcon.
Problem is, that negates your entire starting disadvantage. It means you start with a SAM, better fighter, better rocket, better spacegun. Only a shortage of spacemen saves us.
I mean having a bigger rocket is pointless if the small one is already huge.
Actually? Yes. Not all in one go, but most space stations are modular anyway. If it can lift a capsule capable of making a moon landing and then coming back to space, it can lift a space station module up. It'd probably take a separate trip per module and then either some work on automatic docking technology or sending some people up there to put everything together, but it'd be totally possible.
Actually, it's Yes. And all in one go. Skylab was enormous. It weighted 80 tonnes, and had 1/3 the volume of the ISS. It was four times bigger than early Russian space stations. In fact, it was only 10% smaller than the entire Mir station.
