Never, ever going to happen. Wrong game. The whole purpose of this game is to create one persistent history.
*Facepalm*
You are so adamant on your position your ignoring positions that have vague similarities to the one you reject.
No need for a reset. There are other ways. Invasions, for example. Or just systematic changes in rogue coding. Dwilight, for example: a cycle could be made so that one of the mini-continents was always peaking with rogues, the other declining, to drive some constant ebb and flow between them.
Or my idea of rotating continent freezes pushing people into new playing experiences, forced down-time, and long-term scheduled play.
Don't knock ideas because they have the same first letter as "reset." If you really think our ONLY problem is player density then I want what you're smoking. The political structures created by players on many continents ARE PART OF THE PROBLEM.
