Invisible City Productions has been posting free, monthly, print-and-play games for 10 years now.  December 2009’s game will be the last one posted for the foreseeable future.

According to Jonathan Leistiko, this isn’t the end of ICP. Right now he’s working on a book titled “The Philosophy of Game Design”, which he’ll be posting updates, excerpts, and extras on the site.

Jonathan has a lot more going on in his gaming life than just this. You can read his full announcement here.
