Thanks Puzz3D, for explaining. I just wish gameplay won over realism in that case, and too bad LongJohn didn't find that bug in the AI.

What ToranagaSama in his rather arrogant post seems to forget, is that the AI in Rome was created by the Creative Assembly, the same people who created his beloved MTW AI. Apparently he likes to chase camping AI armies around the maps, and sees all kinds of "outpositioning" and "intelligent" moves by the AI, which the AI probably did not intend. It's merely following a recipe on army level, something the AI in Rome tries to surpass:

Additionally, the AI begins to manuever *individual* units to counter my own. Sorry, despite what you claim, RTW's AI DOES NOT do this!
This is a blatant lie. Rome exhibits unit level AI, medieval doesn't. The only units medieval armies send in piecemeal (like in Rome) are simply the ones that are closest after they have repositioned to face the players army (whichever direction they believe is appropriate).

The maps in STW and MTW are restricted, limited in amount, and certainly not the thousands of possible in RTW. That a map gives a more advanced AI more abilities to make mistakes, does not mean a less advanced AI is better. It simply means it has less opportunities to mess up.

Your love of the MTW AI does not mean that MTW's AI is superior. I'm not saying RTW AI is better, but it does handle more features, so must be more advanced.
