I've played some more with it, and am now convinced the AI in RTW is great compared to that of IG.
I was playing the second battle, I had 2 light infantry occupying the houses and put the rest of my army on the hill, infantry in squares just before the cannons. The AI tried to attack the buildings with horses of course the unit got shot to pieces, it then tried to take them with several other units, they did manage to kill everyone in one house, but I was in time to send another unit in, so they gained nothing but lost a whole lot. The main force didn't move but rearranged a lot, eventually i got tired of waiting and sent my three units of cav towards their cannons (just to see if they could make it. The AI withdrew it's cannons into it's infantry line After my cav got murdered, partly because they retreaded within cannon range and got blown up, instead of following my orders to retreat back to the main force. The AI decided to send in everything it got, I won of course, but I noticed several of my units didn't follow my orders, they just stood there while behind there backs another unit was getting slaughtered, and they didn't respond when i sent them in

This game needs some serious work, it's buggier than RTW before the patch.

I also went by there official message board, we're being VERY nice to the game here compared to them, I'm surprised Eidos keeps all those posts, maybe they've given up on the game already
