New game mode, Career: the same kitty goes on (for example) 3 missions on different moons, keeping the tech tree progress between them:
- Short mission (14-20 days) on a planet with lots of plants, long days and a lot of rain, but almost no scrap metal and very little ore. LIMITED ARTIFACTS! Only 4-5, and after discovering them no new ones appear - so the tech tree will be very basic.
- Medium difficulty - similar to current game. Only difference is limited artifacts, again (4-7?) - so that it's not yet possible to research everything.
- A dry, dusty planet with long nights, tons of rocks and metal. Longer mission, in the 30-60 days range. Now the artifacts appear in normal quantities, just like in Normal game.
Could be that leaving the moon is mandatory (needs to be done before the end of the day) in missions 1 & 2, or not - there will be no tech progress anyway.
