The following are links to reviews of some free RPGs, that are available for download on the web. Freeweb RPGs tend to get a hard time, either being ignored or maligned as incomplete, poorly desinged, or substandard. So, I have made it a personal mission to bring together some reviews and links for a few of the better games out there.
 
Mythweaver
Playability, game balance and fun are key in this streamlined take on the generic fantasy game

Earth of the Fourth Sun
A slightly different take on magic and a unique resolutiuon mechanic make Earth of the Fourth Sun worth a look.

Zenobia
A rules lite, setting heavy game full of remarkably rich world-detail and original ideas.
