Check out: http://www.onrpg.com/ for a massive list of Free MMORPG's.

My personal favorite is Anarchy Online allthough I stopped playing the free edition and upgraded to Shadowlands three weeks ago...

I'm also following the developlemnt of Planeshift. It's a long way from maturity yey, but it seems very promising allready and is more of less playable even in version 0.3!

Yes, Planeshift looks good, but probably it will takes a long time before it will become fully functional... At the moment it's more like a "3D chat"... I hope they'll speed up the development!

Kingdom of Loathing should count. Urban dead definately counts.

Well KoL is the only one I've played.

KalOnline has an English version too. Translations are a bit off sometimes but are usually quite good. Some buttons display as Korean at times but you can easily guess what's what. I haven't played in ages and that problem might have already been fixed. It's a good game if not a little bit boring after a while.

Worth a try, graphics are great and was a muck load of fun at first.

@AnarchyOnline - I tried it for a while and got really bored after the first few hours. It's really grind based and all of the cool features I heard about (purchasing houses,bikes etc) are only for thoose that dedicated their lives to the game. I think I got to level 5 before becoming overly bored.

Yes, I have Anarchy Online also (the free version) and I must agree with magic, the crafting system was a little....weird but it was rather neat, but I just never really cared too much for it, but I must say, Anarchy Online, so far, has the best GM's I've seen in a game, they are verry helpful and friendly, and normally get to you tithin 5 minutes after you ask for help.

I'l check out KoL, I think I've heard about it somewhere before...its the one with stick figures right? Looks rather funny ^_^

Ohhh, Kal Online is rather fun! ^_^

Yes, do check out Kingdom of Loathing. I haven't played it in a while, but I used to be super addicted to it. Great time-waster but the amount of daily credits kept the amount of time I spent on it down to an almost healthy amount. I love the weird humour on that one. Iirc, I'm a level nine Accordion Thief, but I can't remember what I'm called right now.

A Tale In The Desert.
It's free to download, but not to play, there's no fighting, but I simply love the game, it's fantastic, with a great community, and a wealth of options.

For the free one...
Guild Wars, you have to buy it, but it's absolutly free to play, although you can pay for extra items and etc. in the game, it's incredibly enjoyable all around.

Ultima Online - Free shards

Find version of UO on the internet, download (must have dsl/cable)
Download Uogateway

play on free shards. Very easy and fun, don't need a top of the line computer. I used to play with my dell 400 10hd 256k ram.

It has hooked my interest...

Along those kind of multiplayer community sims, I'm kinda interested to see where they go with Animal Crossing DS online...
