I'll put decent amounts of TN on each non-Earth body to make sure there was a reason why your faction colonized that rock. It will also mean that each faction will have their civilian economy jump-start to life immediately.
3B is clearly winning, so ColCost 0 for all.
Dayyālu wants Mars,
Hellraiser wants Europa,
tindrli wants Ganymede,
Kalin wants Venus, what about the rest of you? Possible choices are:
Luna (but that is literally Earth's back door, even TL3 lasers can reach Luna from Earth orbit)
Mercury
Io
Callisto, problem with these two is that they are right next door to Europa and Ganymede, so expect border conflict with other players
Titan, will never reach colony cost 0 and as it orbits Saturn, it is somewhat far from Earth
As for ships, 7A is currently winning 2-1 against 7B.
One more point is tech level. I propose that all players start with general TL1, meaning the first Trans-Newtonian step on each tech. Alternatively we could put in a limit like 10,001 RP, meaning that each player has research everything that is cheaper than 10,000 RP. That would mean that everyone starts with Jump Tech researched and we would skip any arguments over real estate in Sol. Finally, do we start with Geo survey done or not?
