So I started thinking about the tech tree and colony parts and i've come to the realization that a sistem purely based on science points would be a little bit boring, why? because colonies will probably generate more science than landing missions and exploration so once you know colony mechanics it would be easy just to throw colonies and let them generate science passively than actively exploring planets.
A different (small) tech tree for each celestial body exclusively for colonies and it works like this:
You visit a planet (let's say duna) and collect science and planet data if you get for example 3 athmosphere readings in different altitudes you'll unlock pressurized habitation modules and if you do seismic readings and ground temperatur scans you could be on your way to geothermal energy generators the idea of this system is for you to be able to progress more explicitly than just going somewhere and collecting points beacause why would looking at the mun rocks of 10 different biomes allow you to make an advanced habitation module that works ona planet you've never been to before.
Thanks for coming to my ted talk
