I have posted some screenshots of Mount&Blade on the 3rd person/adventure category. I was not very sure where to put them, because it can be played both in third or in first person depending on you preferences, and also, you play it as a FPS when in combat but as a RPG when in travel from town to town.
It's a very original game (at least for me, I don't know of any like this). You have to get a life in a medieval world fighting against bandits, helping people, being a bandit, or joining one of the factions in war and lot more. All combats are done with medieval weapons. What people use to like the most is that you can combat rinding a horse. There is nothing like swinging your sword over your poor enemy as you pass by at full speed with you war horse
It's done by an independent team of developers. They are in contact with the people through their forum, making the game bigger and bigger with each version release. Some of the forum members use to play in stereoscopic, so it looks like the developers take care of making it stereo compatible.
There is a free demo. It's quiet long. You can play till your character reach a certain level. Then you can create a new game or pay for a serial number to go on the same game. It's quiet inexpensive anyway ( I think it was below 20 euros when I bought a serial number from them), and it's very addictive at the beginning.

(I'm not related to them, I just like the game and how it's being developed)
