This is not a bad game at all. I definitely appreciate its tone and the underlying philosophy. Everything one needs to play is contained in one book, which is always a good thing. I haven't had a chance to play the game yet, but from what I've gleaned from skimming through the book, the system seems to be a solid interpretation of the OGL.
Although the layout is decent, I was a bit disappointed by the interior art. I know that illustrations are expensive to come by, so I don't fault a small press too much for not having art that leaps off the page. I guess I would've been more impressed if this product had deviated a bit further from the OGL. Instead of classes, what if one picked a race and a series of trademarks? That would've been more interesting.
Taking everything into consideration, I think that The Secret Fire is a solid game.
