That looks like most (if not all) of them.

I remember that they are listed inside one of the assemblies (.dll files) but I don't currently have the needed software installed to look for it.

The Major factions & their affinities have a lot hard code powering them, which cannot be edited, but a few aspects can be.

I found the list of commands by browsing the assembly like CyRob said. I dont know if this is a complete list but theres a good chance it is.

• TransferResources
• CreateSenator
• UnlockPolitics
• SetInitialPoliticsSupport
• SetGovernment
• AddHomeSystemRepresentatives
• CreateHomeSystemImprovement
• CreateFleet_HomeSystem
• CreateFleet
• CreateMotherships
• StartTemporaryEffect
• UnlockTechnology
• UnlockLaw
• ActivateLaw
• UnlockShipDesign
• UnlockBattleAction
• RecruitHero
• SetHomePlanetDepletion
• SetHomeSystemManpowerPercentage
• SetFleetsManpowerPercentage
• UnlockPlay
• AddMinorPopulation
• RevealNeighbours

Not sure if this is what you mean, but ~line 1050 in QuestDefinitions[Cravers].xml, I see a bunch of what I assume are commands.

For example:

Action_SpawnPopulation

Action_SpawnCuriousity

There are others, like Action_TransferResources (which I assume is the same as what you already listed at the top)

Is that what you were talking about?
