Btw. Can anyone pinpoint actual sources of the power creep?
The only thing that comes up to my mind are Ascensions. They are stupidly overloaded with modifiers that they never needed.
But other than that?
I can't remember the version numbers, so I'll use the DLC they came with for this list of some of the most noticeable sources of powercreep that I can remember:
Biogenesis
- Efficiency stacks multiplicative with output bonuses.
- Astral Siphon Building
- Job Swaps (What was previously buildings with a few special jobs now convert normal jobs into said special jobs)
- Number of researchers on planets are no longer capped by building slots
- Civilians
- Access to ludicrous amounts of otherwise rare resources (Mostly Astral Threads as it enables the astral edicts, but also to a lesser extent Minor Artifacts (Archaeotech is not very good, except for maybe nanomissiles))
- Infinite Strategic Resources
- Support Districts
- Automation Buildings
- Increased maximum Pop Growth
- Luxury Housing
Grand Archive
- Empire-wide buffs from the Grand Archive and Specimens
- Curator relics
Astral Planes
- Astral Rifts (Can give relics and other bonuses)
- Astral Actions (Psionic Fleet in particular)
- Formless
Galactic Paragons
- Destiny traits and better traits in general
Machine Age
- Exotic Fuel Consumption trait.
All
- New unique systems with powerful rewards
- New colony events with powerful rewards
I probably missed a lot of them, but as you can see it is not just ascensions, though ascension obviously is the main source of powercreep.
