Steam Demo Video
http://store.steampowered.com/app/900682/You are a commander/fighter type thing wanting to do something blah blah blah towns. Bandits all over, and you try to take over things. (As you can tell, I don't have interest in storyline, but I think there is one. Also meaning, it's not one of those games that forces you to follow a storyline.)
I haven't played as a merchant, but I think that's also an option, Instead of commander/fighter.
I'm having trouble describing it so, yea, I find it fun, my friends find it fun, thought I'd share.
You can get a demo from steam that I know of, I haven't checked their website.
The cool thing about the demo is that you don't lose any gameplay, it just restricts you to playing past level 8 or something.
etc, etc, WOBSITE
