Having done a spiel on Guild Wars I think it's only right that I give this little gem a plug also. Mount & Blade has a similar sort of game 'cybernity' to it, but is different in almost every detail.
The game exists entirely online, and you can play for free by simply downloading and running the client program through your web browser. This opens up a 3D world that you move through, with 'neutral' cities in which to interact.
But there is also the violent wilderness, where opposing individuals and parties roam and make slay and enslave each other. The combats you have are against both the 'automated' population of the game universe, as well as the forces of other players.
There is no magic. The whole platform is geared to giving you graphic tactical and individual level combat scenarios set in medieval harshness. And, unlike Guildwars and Warhammer (D&D) games, it creates blow by blow battles. It is more like the old 'Top Secret' type combat system than the narrative style of D&D and Call of Cthulhu. It is a world full of greys and browns.
It is created by a turkish husband and wife team, and maybe this goes someway to explaining the original 'feel' of the game system and its cyberverse. It's only a beta version, but has got a pretty loyal band of fanatical followers.
Anyway, I liked what little I have seen so far and hope to have a chance to write of the game play of this game in future also.
Here's a link to the main portal, from which you can download the client.
