Tried posting the video this time instead of a link to the news page.
Some welcome changes to the Lithoid species pack - tweaks to their unique origin, tweaks to Terravore to make it less fiddly. A new advanced space racism civic! (This is one of the weirder parts of talking about Stellaris.) Personally I'm a bit underwhelmed by the new portrait; It's good art, but I really prefer more out there non-humanoid designs, which is the opposite of what they're going for here. The quality of life changes to ascension perks and gestalt nodes are welcome as well. This kind of tidying up is why I like the whole concept of the custodian team.
Only real negative thing here is the increase on price for some older DLCs. It's only two dollars, and they are tweaking them to be better, but I still feel like it's gonna cause unnecessary backlash for little gain.
