A lot of my friends have kids and a lot of those kids are getting to be the age where they're wanting to get in on mom and/or dad's gaming hobby. As such, there's a growing industry of games designed just for those age groups to help usher young players into gaming. Young Wizards is just such a game. It's a tabletop RPG that's up on Kickstarter now.
The game uses cards for pretty much all aspects of the game. Each player has a deck of cards that they use for their spells, equipment, and other things like character race. This deck will grow and change as your character levels and learns new things.
The enemies are also represented by a deck of cards. So it's really easy and quick for the GM to put together an encounter and send their party in a-swinging and spell-slinging versus various foes. Granted, the system is also able to be run GM-less, if everyone wants to just play a character, instead.
The campaign is up and running now and is set to do so for another 20 days.
