Honestly down from STW to MTW2, i think MTW get the best battle AI, while RTW get the worst.

In RTW defensive AI is so broken that they cant even hold their advance defensive position at all. You can often use the "round the hill" trick to reform your formation at a distance to the AI, by rotating it step by step, the AI will eventually re-position their lineup from the top of the mountain down to the bottom!!

And not to mention about the unrealistic moving speed in RTW you can just use your carvary or EVEN infantry to round everying on the field.

Also, the battle moral in RTW is so broken that even the toughest professional troop can rout within 30 sec of combact! (as i only play on VH/VH)


Although i cant say MTW2 get very good battle AI atm, but definitely it is way better than RTW in my opinion.
