Where will most of the action take place?

Well from the looks of it, it's either Carthage or Greece. But if they plan to take artistic liberties with the game it can just as well be any other part of the Middle East, Africa or Europe.

 

I'm pretty sure if it were Carthage we would have seen some war elephants or something similar. The enemy faction had horns on their helmets, which is typically associated with European barbarians.

 

To answer your original question I think the action will take place over the borders of the whole Roman Empire and beyond.
The idea of the game is to simulate the way a legion behaved in battle, also from what I've seen so far you're probably not going run around playing diplomat. So the next logical step is to have your character conquer as much of the known world as possible.

 

I don' t know why this reminded me of a history class I once nearly failed... grrrr.

 

A quick glane at Cryteks page revealed this:
"Ryse: Son of Rome tells the story of Marius Titus, a young Roman soldier who witnesses the murder of his family at the hands of barbarian bandits, then travels with the Roman army to Britannia to seek revenge."

I'm guessing the beach landing must be in Britannia. Well that would certainly prove that they took some certain artistic liberties with the facts, since no way in heck did the Saxons have stone fortifications and roman styled catapults.

 

Probably starting in Britannia and then moving around the Empire ?

 

I agree with Concoy, seem a good idea for a long campaign and set different scenario

 

Britannia sound as a good Starting point for sure.

 

I'd have preferred the forest of Allemania but I think it's not so important after all.
