Find the most active 50 players (or however many you think we have that are active) and place characters of theirs on an island the size of Sring-Sri and see what happens.
This quote is from another thread, and it struck me that it might be fun to allow the most active players (as measured by the game itself, based on usage), the opportunity to have one character spawn on a new all-stars island. What would happen if 100% of all newspawns in that area were active/ambitious/competant? It would be an interesting sub-experiment inside the wider experiment.
