I was quite excited when I first started reading The Secret Fire and it includes some very interesting ideas but also some major flaws.
The deal breaker for me is the two different systems for resolving skills (an innovative system using D6's) and the combat system that uses a D20. Why the skill system could not have been carried forward for combat resolution is beyond me. It appears it was decided that this is homage to the original D&D so we must use a D20.
To be honest the game seems to me different areas of the rules to have been designed by different people, then cobbled together.
The production values and artwork are nothing to write home about but acceptable for the price.
