Viracocha is a free (as in free speech) 3d action/rpg game based on Gnoll.
This game has a great and original story focused on a young sicario (ie. a professional hitman) in Peru of both today and XVI century.
These are very early screenshots of Cusco's Plaza de Armas. As you can see, they are trying to stay very close to reality. I must admit I am quite impressed by their modelisation skills.
I am really looking forward the completion of their first demo!
If you need more information don't hesitate to take a look at their website (french only): http://projetviracocha.free.fr/
Note: Gnoll was originally part of Viracocha before they got split in two separate projects.
Note 2: Thanks WT for the screenshots.
