One of the main things you need to properly do an mmorpg is persistent data and a place (database) to store an editable type and number of variables that cover everything from player power levels to skill and class.
One of the members of the UDK community has created a connector between UDK and SQLite, which is free to use and view the source code for. It can be used (within the UDK limit of 64 players per server) to have more complex and persistent data than just INI files.
