Again, Irish... I'm open to suggestions. What do you propose we do instead?

And the point wasn't really to see which of the factions is better. That's an issue no amount of study will satisfy for anyone. It's more a matter of whether Legionary armies are more efficient than Phalanxes.
And again, I support the idea that having a number of battles between Hellenic generals of the various factions again Roman generals will settle this to some extent. It's not so much a tournament in the classic sense, since we (probably) won't have only one winner, but the culture that remains "standing" at the end is declared victorious.
