Last thing. Why aren't we continuing to send waves over time? Two main reasons - one, because we need to see that the servers are maintaining stability over time; adding a lot of players in a short period (in other words, stress testing) can cause stability issues.
Two, our plan is to continue to add servers - but carefully, and in response to demand. We need to monitor that demand and role out servers accordingly. A long-term recipe for MMO failure is to add a lot of servers early on, and then when population decreases, have to close those servers and merge them together.' Stephen Reid.
