Teacher Discussion Forums

I am teaching a cultural anthropology class to American high school students in New Jersey. I have a very tiny budget to work with for materials. Could anyone help me with ideas, simulation games such as BAFA BAFA. I can't afford to purchase the games, but if you could direct me to a website that generously explains the game that would be terrific. Or, if you could it explain it to me through this forum, I would be much obliged.
Thank you,
Susan
