Fortunes Wheel (different from Wheel of Fortune, of course. No Pat Sajak here) is a new RPG system that's up on Kickstarter now and looking for funding love. The system heavily uses Tarot cards, from character development to combat, the cards are there to tell you your fortunes. The system can be used as an add-on to any RPG game you might be playing, but they're developing their own world to be used with the rules as well.
The Kickstarter campaign is looking to fund the Core Fortunes Wheel game book and for the setting book that you can use with it. The setting book is purposefully framework so you can hang your own plot threads on it as you see fit. There's a quickstart version of the system available in the Kickstarter campaign for you to check out.
The campaign is running now and is set to do so for another 22 days.
