While I don't mind the foreign advisors voice overs, that battlefield announcer can get on my nerves.
But all in all, I prefer these voices to
"The Day is OURRRRRRSSSSS!" and "Yes, Strappy Horse"
The RTW voices bothered me far more than these.
and to the OP: If you haven't heard the crazy general speeches from RTW, the next time you play it play a Roman faction and watch for a general with a trait like "Hooting" - that's one of the early signs your general is a bit crazy. Make him your main general and as he gets more demented his pre-battle speeches get funnier. Also, make sure you let Jerusalem rebel and then read the description for the rebels.
