I am a long term player of Medieval (since its release) and for me, Medieval had got a lot of AI - Bugs too...

I totally agree on the point, that two different designer teams must have been at work in both games, as Rome is in some points worse than medieval

- I hate these archers killing my field units instead of shooting at the enemy. A good programmer would have stopped the archers from shooting, especially when I´m moving my Infantry forward for assault

- city pathfinding is less than perfect in Rome

- Castle sieges are (even though there are pathfinding problems) much better in Rome total war. Although the AI is not that intelligent, I at least have the feeling, that I have to defend my castle. I´ve seen enough battles in medieval, where I just hat 50 Pikemen in my Castle with a 800+ army striking from outside, just placing itsself in front of the Gates in order to be slaughtered by castle defense

- Medieval had improved a lot by the available mods, I´ve extensively played BKB Super Mod, Fall of Rome, Hellenic and Napoleonic and I think there is room for improvement with Rome by modding too.

I am looking forward towards RTW mods...lets see what´s out there!
