Hello everyone and welcome to another Stellaris development diary. Now that the 1.7.2 update is out, we can officially start talking about the next update, which has been named 1.8 'Čapek'. This update will include the reworked AI crisis and other changes to crises outlined in
Dev Diary #72. More information will be forthcoming in future dev diaries on the exact nature and release date of 1.8, but for today we'll be going over some changes and improvements to Habitability and Terraforming coming in 1.8.
Habitability ChangesEver since the changes to the habitable planet classes and habitability back in
Heinlein we have continued to discuss habitability, and in particular, the frequency of habitable worlds in the galaxy. A general feeling among the designers has been that habitable planets are too common and do not feel special enough, but that reducing the base number of habitable worlds wasn't really feasible while most empires only had access to colonizing a third of them at the start. We also felt that the sheer abundance of habitable worlds that become available to you when you do achieve the ability to colonize/terraform other climate types also meant that there is little pressure to expand your borders - not when you can triple your planet count simply by utilizing the planets already inside your borders.
For this reason we've decided to make a number of fundamental changes to habitability. First of all, the habitability at which Pops can live on a planet was reduced from 40% to 20%, meaning that by default, most species will be able to colonize most habitable worlds in the galaxy from the very start. We have also changed the actual effects of habitability: Rather than acting as a cap on happiness, it now acts as a modifier on it (in addition to affecting growth, as before), with each 10 points of habitability below 100% reducing happiness by 2.5% (so at the base 20% habitability, a Pop would get -20% to their happiness). This means that while low-habitability planets are possible to colonize, it may not be a good idea to do so unless you have ways to compensate for the negative effects of low habitability.
With these changes, we have cut the base number of habitable worlds in the galaxy in half. For those that prefer to play with more (or even fewer!) habitable worlds, there is of course the habitable worlds slider in galaxy setup as before. Overall, the changes should result in habitable worlds and terraforming candidates feeling like more significant finds in the early game, and contribute to mid and late game friction as empires run out of worlds to colonize inside their borders.
Planetary DepositsAlong with the change to habitability, we have also changed the way resource deposits are generated on habitable worlds. Rather than all habitable worlds having the exact same chance to generate the different kind of resource deposits, we have now broken it up a bit by climate as follows:
Wet Climate planets (Continental, Ocean, Tropical) are more likely to generate food and society research deposits.
Frozen Climate planets (Arctic, Tundra, Alpine) are more likely to generate mineral and engineering research deposits.
Dry Climate planets (Desert, Arid, Savanna) are more likely to generate energy and physics research deposits.
Gaia planets are more likely to generate mixed deposits and strategic resources.
Of course, this does not mean that you will *only* find those types of desposits on such planets - it simply means they are more likely to be found there.
Terraforming Interface ImprovementsAlso coming in 1.8 are a couple changes to improve Terraforming and Terraforming Candidates. First of all, we've introduced a concept called 'significant planetary modifiers'. This is a flag (accessible to modders) that can be set on any planetary modifier, and will result in that planet appearing in the Expansion Planner even if it not of a habitable planet class. For now, the only significant modifier is Terraforming Candidates (such as Mars), so you should no longer find a Terraforming Candidate only to forget which system it is located in, but we expect to make more use of this functionality in the future.
We also spent some time cleaning up the Terraforming interface in general, hiding the button for planets where it is never applicable (such as non-Terraforming Candidate barren worlds) and improving the sorting and style of the actual terraforming window.
That's all for now! Next week we'll be talking about some significant changes coming in the area of genetic modification.
