imagine a world...at the end of the world...
Basically, mob spawn rates are crazy. Night is longer than day, and 3 times as many mobs spawn, and creepers are MUCH for common AND have the IQ of a zombie. Griefing is illegal, but creeper explosions still happen. Explosions are also larger than normal.
This would be on a different server. I doubt we can, but this is just a suggestion.
EDIT: i can make the map and you edit it if you want
