I have been only able to have a cursory look over the Heroes of Adventure books, but I am seriously stunned a game this good is available for free! I've never been very interested in OSR-style games, but HoA might be the one for me. Thank you so much!

Hey there, thanks for the kind comments. Let us know if you ever get round to running a game and what you thought of it (and welcome to the OSR community).
