Light

[Voldengrath]

Lightness and Darkness is a must.
Also, we need street lamps and things like that.

And maybe! on some days, the stone goes out for periods of longer time
and there is turmoil !!!!

Nahhhhhhhhhhh  

but definately we need day and night cycles as well as street lamps

[LeLu]

Daytime and night time monsters and or mosters that appear for frequently during the day than at night or vise versa. And like Secret of Mana 2, Monsters that sleep during the nighr that we can attack

[Pheonix]

Day and night changes have already been considered and approved
