Graphics wise everything went almost fine for me. Had one CTD at the start of a Bandon Hill battle.

Units as a whole seem to be less cohesive, spreading out over a large area... especially if you run them. Personally I think thats a good thing but it does mean you must be careful of running a unit (infantry or cav) to a point and then immediatly engaging. You need to give them some time to reform. That also makes running down routers more difficult as they're all over the place.

Did seem to have some problem with friendly fire. Lost Bandon Hill the first time as the king got killed by friendly fire. Wasn't terrible and not sure if it wasn't normal as that battle has allies in it and I think it was an ally that got me.

The red line is now the border. You come to it and its like hitting a wall. Only noticed it though while chasing routers.

Combat is still fairly quick. Basic RTW rules of whom should engage whom seem to still apply.

Infantry seemed very fast. Had an extremely difficult time maneurving my cavalry around/past enemy infantry as they'd turn and catch me very quickly. Trying to engage archers with a generals units of cav took almost have the battle map for him to catch them.

Overall seems very good. Looking forward BI whens its released. Unfortunately for me I'm more interested in the campaign map part of the game then the battles, but was still fun fighting with the new units. (Enjoyed the night battle with the glowing lights all around. )

Oh, and played the battles on Hard. Haven't tried very hard yet...
