Over on Stargazer's World, I caught a whiff of a variant d20 OGL game named Legend by Rule of Cool.
"The Legend system core rulebook is now available! Until December 9th, it
can be accessed on a pay-what-you-want basis. All proceeds from the
book go to benefit Child’s Play." - quoted from site.
Check it out, donate (it's a good cause), and download. It is an interesting take on the conventional d20 rules set, with subtle changes that reflect an interesting take on the OGL (through pg30 ATM). Perhaps a review once I finish Savage Worlds. Also, additional material is promised as financial goals are reached.
