Anyone remembers Shards of Destiny? Gracia Final... I think there were ~200 users on first day, it had a lot of potential, lots of unique features that I yet have to see in another server and many more things, but it terribly failed... after 3 days or so, it was completely dead
I don't know what they did to screw up balance so badly to the point of playing something that was not L2, but just so you see, if you put enough features and really work on your server instead of lame plug and play, you may get 200 users to join (being very optimistic).
