When release time comes I recommend this (this is where iEra messed up):
Release a free version first, not the paid like Era iPhone. This way everyone can download it, and you will get a huge income of players from the other Graal iPhone servers. Also, contact an administrator over at
TouchArcade to review it on the main page, where there are over 75k members on the iPod specific website can see. Plus, that website has a strong Graal iPhone community.
Also, do what Era iPhone did. For the first 1k players to join, give them something special. iEra gave them a hat,which is exclusive and will never be released. That way theres a reason to download the app.
