^^^^yeah, he explained it better
I'm not sure if this is what you mean..but if different servers were brought online at different times, each having different info, then basically you are just playing the same scenario over and over..to an extent..Its better to have one persistant world then 5 worlds all with different info...because that would just be confusing...Not a whole lot will happen overnight, no matter how fast paced the game is. You WILL however notice a difference if you haven't played for a week and just got back from a vacation or something and find that the vanu empire is overrunning everything when before you left, the new conglomerate were dominating everything. All a part of the game, it will all balance out. I wouldn't worry about overnight events too much.
