Just a little idea that has been stuck in my head for a while. Thinking about making an actual story of it but for now here's just some mlp versions of the factions intros for Rome Total War. Let me know what you think.

Earth Pony

Bulls… I hate bulls. My grandfather hated them to, even before they put out his eyes.

Did you think I'd be out here on the frontier without good reason? Yes, Equestria needs a strong frontier. No, Equestria does not need unwashed barbarians at her gates! So that's why I'm here, the leader of the Earth ponies, to bring Equestrian order to stinking buffalo. Revenge… that would be good to.

This war against the buffalo won't last long and when it's done I got plans. This is all about power, power in Canterlot. Going down that rode means dealing with all my rivals. The council, the Griffins, those Zebra and their elephant allies. The Pegasi and Unicorn factions to.

After all, the pony who controls Equestria controls the world and one day I will be emperor.

Pegasi

We Pegasi are the only true Equestrians.

We saved Canterlot, we drove out the princesses, we made the Republic! For that we deserve respect… respect and know what is best for Equestria. New lands, living space, territory, slaves! I know what must be done.

The Griffins, they look down their perfume beaks at all Equestrians and they hate us. I'm going to give them a reason for hate, when I have crushed them! Equestrian steel… that is the answer. Equestrian steel in a Pegasi hoof! And the other "great" Equestrian factions. The Unicorns, trash! They have no respect for proper Equestrian ways, for us. The Earth ponies prostitute themselves! As if the ponies mattered, bah.

We Pegusi must lead Equestria.

Unicorn

My faction, the unicorns are beloved by the stars. A proud boast but true all the same. In return we have served Equestria, ruled well, led her armies to glory! It has cost us dearly despite the love of the stars. Some times the hatred of ponies is stronger.

Our dead lie in many graves put there by Zebra hooves and a few Griffin talons as well. Even Equestrian blades have taken Unicorn lives. That we do not forget… or forgive.

So now our time hass come. The spirits of the dead cry out for blood! I will lead my faction in this undertaking. The stars will grant us vengeance.

when Hoofrica is Equestrian. When the Zebras are crushed. When the other Equestrian factions are gone. When the world is mine! Then I shall stand before the stars and be worthy of their love and worthy to rule Equestria.

Greeks

The Griffins could rule the world. Gríofa did. He took a Griffin army to the edge of broken Leylands, there was nothing left to conquer. The world was his.

But Gríofa is dead. His empire is gone. So now we live in evil days. Griffins turn on each other instead of their proper enemies, those who envy all the Griffins have done. Gríofa must weep, if the dead weep. I would weep in his place, but I would also hope.

The world turns. What was may come again. The fates still spin the webs of our lives. So now the stars wish Griffins to be great again. Perhaps a new Gríofa will take up the talons, bring order where there is chaos; remake the world into a better place…

Perhaps...
