Path of the elders game

http://www.pathoftheelders.com/game/
Description: An interactive adventure game that kind of reminds me of the legend of Zelda. Your character walks around a territory with the goal of learning about the people of the region at the time that they signed a treaty. At certain points when you run into someone, there are opportunities to talk to elders, look at maps, and other activities, and a lot of authentic archived footage is available. Students would really get into this, and it is very high quality, rather than the low-budget type of websites we often associate (unfortunately) with educational material.
Additional resources: there are links for teachers, general information, videos, essay material, audio clips available in addition to the game.
