The real question is, will we be able to colonize every planet using the new system. Anotherwords, will it replace this wierd numeric habitabitabily rating system where virtually everything is 0, earth-like is 10, and paradise 26. If you could use ice planets (normally at 3-4) with some technologies like earth-planets, it would blow this system right out the window.
In such case, I suspect that gas giant colonization would come very late in the colonizing tree, or not at all, but I have to admit I'm a bit intrigued at what it will do, especially to the terraforming technologies/neutral benefit.
Will we be seeing both systems at once? Why the heck would you research ice planet colonization for those size 3-4 planets, when you probably can just invade the hapless AI's worlds after they do it for you. |
You will be able to colonise all planets if you research all of the environment techs. Until you get the tech for Ice worlds you cant build a colony on an Ince world.
I don't know if you will be able to invade an existing colony without the tech though, I'm guessing you won't be able to as your troops wouldn't be equiped to fight in the extreme cold.
The Planet Quality (numeric) system is seperate to the planet type. PQ determines usuable land area for construction, not the composition of the atmosphere etc.
As for why would you research an environment tech for a low PQ world - you probably wouldn't. The point is you have to decide which course of action will help you more. Do you research Ice tech or Toxic tech? It will come down to which worlds you have discovered and how good they are. If you don't want to spend time researching a tech for a PQ 4 ball of ice you could either trade for the tech or just ignore the world and go for something else.
