I'm curious how no sleep currently affects MP. I do not seem to be able to recover from any illness (non-Zombification) no matter how well I eat or how many drugs I take. Is sleep required to survive sickness? It should be realistically, but I don't know how it is implemented in MP right now. I actually have no problem with no sleep in MP right now. I rarely move at night because it is far too dangerous (my screen is usually very, very dark; I don't gamma cheat), so I effectively am immobilized equivalently to sleeping. My only complaint is I would really like the chance to recover from illness if all I have is a common cold. It's frustrating to lose a very nice character because you sat in the rain a tad too long. As for the effect while sleeping, there is no need for complete darkness and removed control. Just make the black Fog of War close in completely around the character so you can only see the small bubble around you (akin to the amount you can see behind you while awake, but in a radius around the player; this would simulate the small amount of perception you have while asleep). That way players aren't completely bored and can still manipulate UI elements and such. Obviously no actions could be taken until they wake up. If sleep was implemented in MP, I really hope that either: 1) It is a time compressed sleep; OR 2) You have the option to disable it in the server settings. I would frankly quit playing PZ immediately as soon as I am forced to sit and stare at a blank screen for 30 minutes while my character sleeps. I don't have the time in my life to be wasting it on that sort of nonsense. This is still a game that I am playing for entertainment at the end of the day. I think Minecraft's solution is one possibility for time compressed sleep. Another (and I think superior choice given how time compression is already implemented in singleplayer) is a time compression by vote mechanic which is popular in the Paradox grand strategy games. In those, every player chooses what time compression they would like to be running at, and the server moves at the lowest setting chosen by any single player (the UI shows both the current time compression as well as the one you the player has selected). If the game is paused, it can remain paused for 30 seconds before another player is allowed to unpause. Lastly, you could make an admin command to force time compression if you have trolly players on the server (or I guess you could just kick them).
