That is fair enough. Don't care much for the antiquity myself, though in that respect I look at this game more as an opportunity to gain a new interest.
It will be interesting to see in what way the game differentiates between the various "countries", peoples, or what have you. I strongly suspect that, like with EUIV and CKII, the initial release will offer some variety in mechanics for different cultures, religions, and government types, but leave something to be desired.
EDIT: And later to be adressed through DLCs. I have no problem with this policy in principle. Wouldn't count on every little barbaric tribe to be as fleshed out as the Romans, though.
