EUO (for want of a better name) is a real-time, multiplayer, persistant-world RPG with the look and feel of Ultima 4 and/or 5.
EUO borrows a lot from other RPG's. It uses a UO like skill system without player classes for character definition. Combat is based on D&D dice rolling, with some UO influences. The interface is Ultima 5, while most of the tiles are 'borrowed' from Ultima 4. Magic uses's Ultima 5's word based system, but spells are borrowed from all sorts of games. Random dungeon generation is inspired by nethack.
