For those who haven't seen this video I did, here is an example of BoBII in action.
Now the initial attack from behind on the bombers I'd never get away with in IL2, but if you watch the rest you will get an idea of how good the AI is when under attack.
Also if you watch the titles, you'll see Gun camera footage I made from the game and in it I am chasing a damaged 109 low on the deck. Just as it goes out of view I get into position and when I get onto him he is stalling and goes into the ground.
Now that is impressive AI to make it try a move and then stall...brilliant.
Here's the video:
