Recreate the imperium of man

[Sabaithal]

In this game, what ethics would they use? What civics? Etc.

I was thinking spiritualism, and authoritarianism. Xenophobe and militarism fits them too, but you can't pick all, so I figured the first two would be more important. Imperial government, obviously. Though I suppose oligarcy would work too, considering.

spiritualism authoritarianism and xenophobe probably with a prosperous start and also oligarchy because imperial is stupid in his game.

[Mentato]

You need the Imperial Cult civic, anything else would be a blasphemy against the God-Emperor.

A good second civic can be a Warrior Culture, because everything in Imperium of Man is either military or it's support.

Origin can be Syncretic Evolution to represent the sanctioned demi-humans like Ogryns, and to replace non-fitting Prosperous Unification which was anything but.

Get psionic and receive the chosen one status from the void, then when asked to become god emperor pick the answer yes.

Im guessing this is for the CURRENT Imperium, and not the one the Emperor founded back in the 30K's?
Y'know, the one forged my a Militant-Atheist Psyker-Gesalt, who championed human control, but wasn't above negotiating with Xeno's; who built a Feudal Empire system of Governors controlling their own territories, except for the Imperial Tyth, and mandated only that Science and Reason, not superstition and religion, would be the building blocks of his Empire.
If you want THAT Imperium...
Imperial - Fanatic Militant, Materialist - Warrior Culture, Byzantine Bureaucracy... then add Feudal Society later when you start to expand and conquer.

((In case your wondering about the BB, thats because of the Emperor delegating alot of the bureaucratic work to Malcador the Sigilite))

Authorian, Xenophobe, Spirualist, Slave guilds, Feudal empire, divine cult.
The imperium is not a nice place to live and would collapse without the enternal state of war there in.
