I think Impaler is right, we need more 24 hour cycle things.
Preferably separated by 10 minutes, maybe have 48 of them or so. Also deal direct HHP damage to players who are offline for more then 40 minutes at a time. This solves the problem of potential murder victims being offline and therefore unavailable to be murdered.
The eager murderer simply has to wait by their hearth fire for either the player to log on, or for the dead body to appear from offline HHP damage
BRILLIANT!
