I completed Drakengard for PS2 a couple days ago. The game was janky and bullshit, but it also gave an equal amount of opportunities to cheese. I accidentally broke the ai for final boss (B).

I played this air battle pretty aggressively. While chasing the boss I found a position diagonally behind where I can keep it stuck flying in a big circle. I could just eat its healthbar in peace while the boss was confused and doing nothing.

So, anyone got interesting experiences in breaking enemy behavior?
