I didn't get very far.
The first problem I encountered was that my monitor's resolution (native 1440 x 900) was too small to display the entire screen. I managed to partially fix that by setting my resolution to 1920 x 1080, and even that wasn't quite large enough (cut off the bottom of the mission description, and could only see part of the formation command panel), but it was enough to start the game.
The other problem was that the game would keep crashing. I'm not sure what caused the crashes, though I was always in combat when a crash occurred.
Moving on from bugs, I found it mildly irritating that the prince would rush enemies to attack them, even right after I had given an order. Having melee units move to engage the enemy on their own is great, but only if they were idle beforehand. Ordering the prince to move, only for him to charge the nearest enemy right after I give an order, repeatedly, is annoying.
