I should apologise for the framerate issues in this video, the game was having some problems at points, but it definitely feels worse watching the recording than we did here.
The AI really does seem to need some work, the enemies just don't seem to remember where you have been. They just seem to have a fairly simple set of rules they follow based on what is visible at the start of their turn. This is fine except that the melee troops are both too clever and too stupid. If they can't get close enough with their move they hide. Then they seem to promptly forget where my guys are and revert to random movement unless I have revealed myself to them again during my turn. Here is the Loading Ready Run episode I mentioned in the video by the way.
I also like the tension between wanting to use my "good" characters for strategic roles and needing to keep some back to fight.I have definitely been erring on the side of pushing them into strategic roles and I can see it coming back to bite me later on in the game as the enemy forces grow in power.
