I stayed away from this, WoW and Evercrack because I didn't trust myself to not become completely addicted. A friend of mine in college got into Everquest so badly that he stopped going to class and ended up dropping out. Just not worth it.
Galaxies always seemed like a really cool game though.
I played it for a very brief time after basically everyone turned into Jedi and ran around slicing up the universe. It was a neat game, though probably better before everyone was able to be a Jedi.
