There is a lot of meat here for the asking price of Pay What You Want (so, potentially free, but I'm here to tell you it's worth paying for). Despite some rough edges (particularly with regard to determining acting order in combat), Sharp Swords & Sinister Spells has a lot to recommend it if you're looking for a rules-medium fantasy RPG and especially if you're looking for a rules-medium Open Game Licence RPG. That's right! Sharp Swords & Sinister Spells is released under the OGL, meaning that you can hack it to your heart's content, legally! Seriously, give this game a look.
