Axu's Plays Online World Simulators
The first huge world simulator that I got involved in was BatMUD. I got a good taste of both playing it and writing code for it.
The first commercial MMORPG I played was Ultima Online. I had to quit it though because I suddenly needed to travel a lot in real life. After I settled down again, I didn't feel like starting again.
In 2003 and 2004 I've been playing Eve-Online on and off. My main character is called Kaluan Kalhaan. I made this nifty calculator, which works in the eve-online in-game browser.
2005 spring brought World of Warcraft, and I decided to create a whole new page describing what I do in WoW and where I do it.
