So, another free RPG (a PDF version of course) is aviable at http://www.bigironvault.com/. You can download it from HERE. But wait, what is Mysterious Circumstances? Take a peek:

“Mysterious Circumstances was our first game to hit the market and is Big Iron Vault’s foray into the world of the supernatural. Do you remember that one time that you swear you saw the snowman in your front yard move? Or remember that time when you were home alone and in the corner of your eye you thought you saw someone looking at you? You didn’t tell anyone did you? Maybe you should have told someone, because the next time maybe, just maybe, that “thing” won’t just leave you alone.

Mysterious Circumstances is meant to be a “beer and pretzels” role-playing game based on things that go bump in the night. The players in Mysterious Circumstances play children ranging in ages from junior high to high school. ”
