Btw, remember to tell the sound creators that combat music has to have a few second delay and/or NEVER start full volume, and only start when:
1-The enemy is 2 meters away/very close
2-You hit an enemy
3-30 seconds after the enemy notices you but can't catch you, overridable by point 1,2 and 4.
4-You get hit by an enemy.
Anything else would give away that there's an immediate danger without even seeing it and spoil the fun and the survival aspect of the gameplay.
Oblivion and Morrowind does that BAD. You always know when you are in combat without seing the enemy. Later Fallout games do that better.
