Thought this was worth talking about, albeit briefly.
This is an awesome alternative to the standard initiative order I suggest you read it all, didn't? (you should) but basically everyone rolls initiative and then it is passed around between the players. Its very descriptive and story driven but is heavily waited towards the players, which is fine but i'd like to add more of a chance that a monster can interrupt the flow for dramatic purposes.
Easiest way in my mind to do that is have everyone roll a D6 when they declare who the initiative will be going to next, if they roll 5-6 the initiative is passed to the GM to assign to a monster, they then must roll a D6 in public before declaring who goes next and on a 5-6 the GM may choose another monster, anything else it goes to a Player.
