I have played a bunch of games against Egypt, and I have come to the conclusion that I think its OP.
All the units have splash which helps a ton, snakes seem too easy to produce and give lots of damage.
Just an idea to keep in mind next time your playing Egypt/against it.
Also I think while Romans have good defence units, their attack units aren't very good.
The battering ram and turtle formation are size 3, so the can't maneuver very well, the the other highest units are horse-men and gladiators.
I think the battering-ram/turtle formation should be beefed up a bit, or make a way for spear-men to create a turtle formation and brake it up for better manoeuvrability.
I also have and unit idea:
The Siege TowerEDIT: Of course all this is for after release.
