Rome 1 had some of the best sieges I've ever had the pleasure of playing in a TW game. I've played it
recently as I am one to do every so often for my favorite TW game ever, so those that continue to say the Siege AI was bad or annoying to
me seems like they there is some fiction being peddled. I would advise you, to perhaps you playing them? Hell, I play Rome 1
vanilla sometimes with no mods and I find that fun too.
TWC Siege AI - example showing AI attacking multiple points on wall in order to spread player thin, with more
historicity built in - I've had Rome 1 games where my entire cities were attacked from
all sides and losing epic battles (Siege Equipment can be destroyed forcing AI to retreat, but the AI can continue a Siege and build more to keep the pressure on). It's way more hectic in late game with huge cities, sappers, towers, and ladders.
