[Lord Azagthoth]

I use a house rule for starships (which could be implemented for creatures) which I call Tactical SM. I just wrote down the SM for all sides (top, ventral, left, right, front, and back) and it becomes relevant for the attacker and defender to take tactical postions either to get the best chance of hitting or trying to get the best chance for your attacker to miss.

Instead of Quick Contest Piloting rolls to get this advantage, you have to roll against Tactics or another appropriate skill.
