I've got an idea for a sort of epistolary solo rpg actual play blog series told from the perspective of a protagonist who - much like myself - is a middle-aged out of shape gamer without any particularly notable "adventuring" skills.

I've got an idea for a sort of epistolary solo rpg actual play blog series told from the perspective of a protagonist who - much like myself - is a middle-aged out of shape gamer without any particularly notable "adventuring" skills.

My first instinct was to just rely on various premade solo modules - the Call of Cthulhu "Alone Against" series, Fighting Fantasy gamebooks, Tunnels and Trolls solo modules, etc, convert everything into GURPS, and play the same (generally hapless) character as his skills improve and he grows somewhat competent, creating a linking framework to explain all the genre hopping.

Now, though, I sort of want to expand from "just solo modules" to playing through premade adventures designed for group play. Which tools would you recommend for this? I don't want to deviate from the published details too much - I'm pretty good at compartmentalizing player/GM knowledge - but I'd like something that helps keep me surprised when it comes to NPC actions, particularly in combat.
