[Mike Garber]

Ask your players, and let them decide. Maybe they stay on your server because of the location, the features and the % of chance to meet someone else. If you expand too much too fast they might not meet people as often and get bored and leave for another server.

But I'd suggest you to ask your players what they want instead of having us decide it, and if you follow our advice we might ruin your server. I mean, we don't know your players.
