Is it still possible to join in? If yes: I'm considering if I should, but I've a question first: How fast do you want this game to go? One turn per day, per two days (etc)? I won't be able to do more than one turn in 48 hours, so if you want to go faster than that...
My two cents regarding setup:
1) Galaxy size depending on number of players: <10 medium, >=10 large
2) Galaxy type: I'd prefer spiral arm, but that's just me
3) Tech costs: personally I'd prefer high, but you seem prefer medium, I'm fine with that
