Although I love Fantasy Grounds, and I LOVE the Iron Heroes Ruleset.
DO NOT buy this product. Not until they either update it for Fantasy Grounds 2 or create a D20 JPG extension for FG2.
With every passing update of Fantasy Grounds, this ruleset is become more and more buggy and unplayable, and my group has been playing my Iron Heroes campaign faithfully through Fantasy Grounds for over a year now.
Though Smiteworks has offered me a refund, I did not take it. I really just want to keep on GM'ing my Iron Heroes campaign... and my faithful players feel my pain with each session.
My players would buy this, if it worked. They love playing Iron heroes, the changes in Armor/Magic is awesome, its way more fun being a hero (not a paper-doll layered in Magic Items) If Smite would have kept updating it I'm sure everyone I've GM'ed this game with would have bought the Ruleset.
