The premise of this game format is that if you don't post within a set time, your character dies. For added alacrity, I also suggest a turn based system; if you don't perform your action within one day, you miss your turn. If everyone posts their turn within one day, the next round begins. So several rounds can happen within one day, but no turn can last longer than a day. The format of posts should be concise and limited to a certain formula we can work out; eg, action + dialogue + description, each with less than 50 words. Finally, there will be numbers and a combat/success system, also as simple as possible. There may be sudden death even if you post conscientiously. Yesnomaybe?
