[Unpredlctable]

In addition to what I said earlier, about less/no development resulting in decreasing playercount: when the server starts having something to do and places to go, when players come in see the server, they won't say "Wow, there's nothing to do here; this place is awful," they'll have interest in the server, along with some incentive to stay. Soon enough, the playercount will begin to increase. When there are more players on the server, this will give the developers more motivation (hopefully) to create more for the server. This will result in the playercount increasing more. And so on and so forth.
