I've mostly completed a voidborne inward perfectionist run, and I've been surprised at how close it seems to work out in the end game compared to a more normal start.
I'm a bit behind where I'd normally be since I've been trying to stick to the spirit of the origin and have refused to put any of my organic pops on anything but habitats, and normally by this point I'd have a ringworld or two dedicated to research and some ecumenopoleis for alloys and consumer goods. I've colonized all of the planets in my empire's borders, but only put droids (and now synths) on them, which means slow growth rates. If I built a ringworld I'd do the same and only put robots on it, which feels like an extreme waste of alloys.
Voidborne is excellent for science, and surprisingly unity, at the game start, but it feels like it lags a little behind normal starts after that. Not enough to make it a real handicap though. The real test will be when the crisis arrives in about 20 game years, since I tried cranking it up to 10x, and my fleets aren't as strong as normal.
On a completely different subject, I wish Paradox would work on the loading speed of Stellaris. I genuinely wonder why the game takes so long to start up, since I own no other software (except maybe other games by them) that take so long to start up. Not even things like Unreal Engine's editor takes so long.
It takes maybe 2-3 full minutes to load on my desktop, but on my laptop I clocked it last night and it literally took 11 full minutes for the game to start. Admittedly, that was with some mods since my friends wanted to play multiplayer with those mods, but... is there like a cryptominer installed in this thing now? What is it even doing during startup?
