Time Zones
Times zones will not be a problem (first off this game will be strictly american). but the game itself will have its own time [meaning that it will be 1:00pm even if its 2:00am where you are and 5:00am in another place]. this will eliminate being confused because you will naturaly adjust your time to the game's (time goes by in real time in the game). then when someone says [ex. Lets go raid the oldern castle of Madarial] at 1:00pm, you will know what time that is in your time, and respond accordingly.
