A Civilisation, Hearts of Iron, Stellaris X Mass Effect

Synopsis: After overcoming the challenges of their Homeworld Humanity begins to expand into the stars. What will happen when they emerge onto the Galactic stage through a baptism by fire?

Details:

Fanfiction: Mass effect, Civilisation, Hearts of Iron, Stellaris

Type: Mass Crossover

Elements: All mentioned games, Lessons from the YouTube Channel Templin institute about Tanks, Navies and Invasions as well as Nations for interstellar settings, deep lore if possible.

Notes: Lots of creative freedom if a writer adopts this within reason and the elements provided above.

Rational: I'm honestly surprised no one ever thought of making something like this, each of the sandbox games can effectively act as live repenstations of what your human civilisation looks like.(Civilization for history, HOI for military doctrine and Stellaris for the modern space age) And considering we don't have many Civi-overs I think presenting my idea for a new but also unique take on the trope would be worth mentioning.

As to why I mentioned the Templin Institute and to those who are unaware they are a channel that briefly explores alternative factions, nations, universes and whatever, recently they've done a few video guides on how to create a space navy, a tank force and how to launch a planetary invasion as well as why there useful. I think if anyone is gonna write this kind of story they'll benefit from TI's advice.
