Note: They're PLAYING with the Beta (which is not finished), it is not released or in beta yet.
Already confirmed is MAP MODES.
E: Colonization now requires an influence cost depending on how far from your borders it is- expanding naturally is 'cheap', expanding across the galaxy is 'really expensive'.
E3: Hoo-boy, here are alot of changes upcoming:
Embassies are gone, replaced with trust so depending on how many agreements you have you can build up trust over time. Extensive rework of ethics bonuses
War Philosophies are a new policy that limit your CBs, so if you have Unrestricted Warfare you can use any CB, liberation can only use Liberate
Pacifists have more expensive Conquest CB
Fanatic Pacifists CANNOT use Unrestricted Warfare and therefore cannot wage wars of conquest. Instead they get +15% happiness and pacifist governments grant more core system
Xenophobes get more influence from rivalries
Diplomacy now costs influence. Xenophiles get cheaper diplomacy, since embassies are now removed.
Spiritualists no longer get +Happiness, they now get reduced Ethics Divergence so your Imperium of Man has an easier time hating the xeno, the mutant, the heretic.
E4: No matter what your philosophies you can always reclaim planets that were once yours (make the Blorg Commonality Great Again), and I think they said defensive wars are looser with CBs. Will edit this with more if I notice stuff in the stream that isn't mentioned here.
Other notes:
*Pop up to name colonies once you start colonizing a planet.
*Researching multiple projects at the same time in the situation log is a bug. Not a high priority for fixing but will be fixed eventually. Probably not in 1.2.
Edit 1:
*Ringworld building will likely come in the future. Wiz wants it but no promises.
Edit 2: *Open borders impacts both civilian and military ships
*quite a bit has been moved from the trading screen. Diplomacy looks more paradox GSG then Civ 4x now.
Edit 3: *Slave revolts are incoming in 1.2. Factions seem to be based on how many enslaved pops you have. More details will be coming in a future dev diary.
Edit 4: *on to do list on making debris and other projects that don't cost research points to not pause technology research. Not a high priority.
Edit 5: *Appears to be new colonization messages based on either government or ethics
*closing borders will piss off other nations and certain AI personalities will likely attack if you're boxing them in.
Edit 6: *No new victory conditions in 1.2.
*fix to bug of crisis killing everyone but you resulting in you winning. Now crisis counts as another empire for victory conditions.
Edit 7:
*Fallen Empires do not have open borders. Potentially will in future but fallen empire will try to kill your ships if you enter their territory.
*In the future looking to add more weapon sizes.
Edit 8: *on to do to allow deconstructing space stations and refitting with modules. May make it into 1.2. Wiz is also annoyed by it.
*sectors will no longer build certain spaceport modules (no specifics) in 1.2
