Miss old school Galaxies?
http://www.swgemu.com/This is a project that is basically Galaxies before the major overhauls. After Jump to Lightspeed, but before the Combat Upgrade, and way before the NGE. From what I understand, they have most of the features implemented, though some things (like vehicles) are still only on their internal development server.
We had it running at work briefly yesterday, and the skill tree brought back fond feelings. Seriously, I almost wanted to play again if it wasn't for the constant nagging memories of how barren the worlds were and how unfun the game itself was. But I love the whole skill tree concept of leveling things by actually doing them, and players having the ability to teach things like skills and languages.
