i think this was brought up a few times till now but here i go

this game should have races with bonuses to attack,to defence,to type of ships (small weight,big weight)
and to implement ship chassey (fighter,frigate,etc) also according to the weight.
missions should have more reward types --- hmm like types of minerals also.
id like also researches that take time to open the path to new chassey bigger weapons etc( the experience system on the commander its a great way to substitute researches also and the mining system maybe have em both?).
some special ships that require minerals to make?
and other ideeas like these ones but i know its nearly impossible.
but who knows? sir emi does

PS the best turn based space strategy game i ve ever played thank you spaceo team
