I've often heard the RTW AI panned for being dumb, etc, and I find that it is true to some extent-- the AI does not adapt to player tactics, but as game AIs go, it wasn't the worst, far from it.

My question to people who've played every TW game is: how does the AI of RTW fare against the AI of Shogun, Medieval and Medieval II? Out of all the TW games, the only one I've played extensively is Rome. I've played M2TW only briefly, and have never touched the first two games.
