I saw this a few days ago before there were any responses, and thought about it...got bored, then played Starsector which I think is good enough as it is. Then went back to here and saw you lot getting confused and the OP whining......I sigh....................................Jesus Christ. Couldn't you have made it clear in the OP what you intended, same goes for the title??? It in no way indicates that you will make a game.
(To respond to optimising, you do that after you make the 'draft' game otherwise it just gets complicated and messy however well planned you make it, so go away make a draft of what you want to make then come back and ask us for advice.)
I sound harsh, yes, that is because I am frankly bored of silly little posts and misunderstandings. BE CLEAR WHEN YOU POST.
(I am also very tired and slightly Ill so if this offends tough idc and my logic is mildly broken
)
All in all......bleh I give up on trying to understand people
