If the guy who does the RPG lorebooks is here, I have really been enjoying your stuff. I'm running Rise of the Runelords and I'm impressed on how well it handles a solo playthrough. Making the NPCs into a makeshift party like one of the pathfinder video games is pretty cool.
Also if you're taking recommendations, I would love to see the advanced players guide and advanced class guide get added so that I can have access to all the 1E classes.
