True,
1. Having been thinking that maybe natives are scientist groups that have 'gone bush' disappeared into underground colonies themselves - they would want to trade goods for research. But wouldn't be visible until you 'stumbled' upon them, hence the need to explore as the map would already be known.
Also - Goodie boxes are supply drops. basically a race with other players.
6. Instead of missionaries and religion (as Col is only Christian), then diplomats and trade mediator. Underground scientist groups would then only trade essentially with players of good relations, or only when a 'mission station' is built by a diplomat.
2. Ref probably would use nuclear weapons - making plantary defences important (makes sure you want to defeat the ManOWar) but would only be added to REF if you 'really' pissed off your king.
3. Agree with you totally!
4. I figured 'basic food' and 'quality food' as two different trade types. But water as well. Water in aquifiers to be mined (or removed from permafrost which is harder). That can be processed into more air and fuel.
5. Pirates are a good option. Scientist groups that don't like anyone!
7. A graphic of global zooom like in Civ4 would be cool, then tilting the globe so that you can see orbits and craft icons (and the two moons). Failing that, using a massively modified
Different latitudes on the surface would require more fuel to launch into orbit, and different air/space craft:
7a - 'shuttles' would be used for orbit and and one shot transportation runs anywhere on the surface. People and cargo are seperate or not!
7b - 'galleons' are the empty ships in orbit that brough the colonists and/or cargo. Huge fuel expenditure = 6-9 week one way trip. 'economic trip' means different times of the year and 6-9 months.
maybe in this game constructing your own craft to return to Earth isn't viable, just building shuttles. But subsidies and trade back (no idea what yet) would enable more galleon type craft. Or initial purchase of goods costs much more as you pay money for new ships. but then you can refit using your own industry to send back.
8. Turns - Mars has a year just on twice Earth. So one turn = 2 months earth time, 1 month Mars time (i always play Marathon

)
