One of the things that's made me happy as a board game designer has been Board Game Geek, the ultimate encyclopedic compendium of tens of thousands of board and card game. It's the site if you want to know anything about board games. Hardly a day goes by where I'm not looking something up on it.
So the roleplaying game designer in me is particularly happy about this: the upcoming debut of RPG Geek, which is just like Board Game Geek for RPGs. There are 3200 entries for 1000 systems currently being slated for construction.
There's an open beta starting very soon, and a call for entry development will likely go out shortly thereafter. So if you ever wanted to help transfer all that Pathfinder or D&D or any other RPG content into a massive database, this is your chance.
You can sign up for the open beta here and read about the project here and here.
This is a very big project, but I think it will be very, very cool.
And also woefully underdeveloped on the Pathfinder front. None of the Adventure Paths are in there, for example. Anybody feel like taking that challenge on?
