I came to the RPG/OSR blog scene later than many others so this has probably been covered before but I thought I would just give a shout out to one of the games that you should play if you have not already done so.
The Library is the storehouse of free pdf files for most (all?) of the rules and resource volumes released in the life of the Talislanta game. It is a shame that Talislanta is no longer in print but it is awesome that the creator has made all of this stuff available for free. If you have never visited the site or explored the world and rules of Talislanta, follow the link and enjoy.
