I downloaded the demo one of the first days after its release, but I haven't got any farther than playing the tutorial, so, no, I don't think I am very excited about RTW yet.
But I'll buy the game as soon as possible anyway, because I want to join the "PBM team" that will start a PBM thread for each of the Roman factions. It surely looks fun to me playing a faction (or more general "a game") for the very first time and report on that in a PBM thread.
