I've played Medieval:TW for quite some time now and I'm considering buying Rome:TW. Particularily it sounds like an interesting because antique history is so much more interesting (in my opinion anyway)

However I've got some doubts. One person I talked to about it hates it, saying that for example there is no attack/defend setup like in M:TW and that tactics and strategic thinking aren't really required in Rome.

I can't really say that I'm bothered about graphics, even though they're impressive it's not a reason for me to buy a game. What is very important IMO is unique units- the more the better, one reason why I never got into Shogun: TW.
So what do you think?
