"re: 12 - you misspelled "Homunculi" (I think)"
I pluralized "homonculus" (or is it "homonculous"?). I will check the spelling later, but I am fairly certain I spelled it correctly. And no Kodos, that is not at all what I was making.
"re: 24 - Remember not to split the engines into different component families, otherwise players could add one of each (positive) type of engine and get huge bonuses"
They are all in one family, so it is not a problem.
"re: 32 - so now shouldn't they be Neutron Cannon (ST)?"
No, as they still destroy Security Station components. It is just aesthetic; how do you "kill" a station? The station technically remains intact, but the security personnel die, so you get the effect of the SS being destroyed.
