I've been giving the quick combat rules some thought. On one hand I want to try them, on the other I just don't see myself only using them in a game. So I began thinking about how I could use both. When would the transition make sense?
So here is my idea, any time the player making an attack or combat roll of any kind aces a set number of times they get to go into quick combat mode as a kind of critical.
For example a GM could set the number at 4, any combat roll in that game that aces more that four times the player describes the dramatic combat by totally going Martin Riggs or john McClane and wrecking the whole scene.
