The Fish MMO framework is heavily inspired by games like EverQuest and Ultima Online. The goal is to create an easy-to-use template for building massive multiplayer games.
There is currently a Login, World, and Scene server type with plans for more.

Login Server:
Scalable Design, multiple login servers can be launched at the same time to help with load balancing. The client simply needs a list of servers.
Account Authentication
Account Global Character Creation (Characters can be used on any World)
Character Selection/Deletion
World Server Selection, the login server reads World Server details from the database instead of keeping a socket open to the world servers.

World Server:
