A fix for Galindell's mod until it is updated; https://mods.factorio.com/mod/galindell-world "Life is Factorio. 12 factions are fighting for the planet. 4 aliens, 4 human, 4 robotic."
Mods introducing new content into the game.
Changes to enemies or entirely new enemies to deal with.
Are you planning on doing creep for the humans and robots?
Rampant intergration?
I'll probably write my own mod inspired by this one and plan for those features.
