There would be no posting or activity requirements at all. The players decide on a lynch, or have it decided for them at random. Play or die, essentially; I don't think any other regulation should be necessary.
What do you guys think? I think it might liven up the game a bit, and make people take action a little more early and often (for later Days, as well as the first). But, maybe I am mistaken, and perhaps this is a solution in need of a problem? Maybe it is too harsh, too potentially unbalancing, or too easily abused/exploited?
Note: I think ideas similar to this may have been tried, with limited success. I know the semi-random ending of Days was tried at least once (but, I think that had a little prior notice, in some form). I am not sure on the randomized mod-kill part though.
I think it has merit, but my preferred method is actually to do away with the connection between night actions and days.
Put NAs on a cycle. Say Scum get 1 NK every 7 days (like a cooldown) but Doctors can protect someone every day. Cops can only use their action say every 10 - 14 days (as I believe it's an overpowered ability).
That way town can dawdle all they want (and scum may actually try to keep the game slow) but the longer they wait to make lynches the more NKs will pile up.
But anything that forces people to act is a good thing in my book.
