Leave for dead
When fighting an enemy, sometimes you can get lucky and knock them unconscious. This allows them to be looted. This is great, but the only way to then exit combat is to either run away (leaving the hex) or killing the enemy.
How about an option (which mobs have, too) to leave them for dead, stay in the same hex, but just close the battle screen, leaving the character free to do whatever they want. . Next round the combat could begin again, and if the enemy has regained consciousness, this could lead to "fun".
Overall, this would allow a less lethal play style to be adapted, and lead to more fun moments when an enemy ends up doing this to you.
