Even though board and card games are growing in popularity in recent years, I still get asked from time to time about where I find so many unique games. I usually direct them to the Boardgame
Geek website. It's an amazing collection of information on all these games that never make it to the shelves of Wal-Mart.
I just put up a "geeklist" there about my flipcharts too. Check it out if you want to get started researching the games that those flipchart activities are based on.
