My kids start school tomorrow, so to give myself one less thing to worry about then, I've decided to post tomorrow's question along with today's. And as you'll see, they're closely related questions.
My regular weekly blog will still be posted Wednesday or Thursday. This week's installment will feature a new "Time of the Tarrasque" session.
15th) Which RPG do you enjoy adapting the most?
Call of Cthulhu. Apart from trying one of the brief solo adventures back in college (when my roommate owned a copy), I have never played Call of Cthulhu using Chaosium's original BRP rules. I have, however, acquired a sizable CoC library, and have adapted it for use in other game systems: I ran a couple short GURPS campaigns using the rules in GURPS CthulhuPunk; I've co-written a short, silly LARP titled "Miskatonic Regional Elementary School"; and I've run three campaigns in Green Ronin's Freeport setting, which is steeped in Lovecraftian horror. I'm also partly responsible for the volume of Cthulhu Mythos elements that appeared in the long-time Buffy campaign I played in; my first character pitch was a essentially a Deep One hybrid, and the GM gleefully ran with it.
16th) Which RPG do you enjoy using as-is?
That's a tough question, as I tend to make up my own material for almost every system that I play for any significant length of time. But at the moment, I'd have to say Dungeons & Dragons, Fifth Edition. Most of my homebrewing efforts are currently dedicated to my Pathfinder campaign, so for now, I just use what's in the 5E core rulebooks and the canned adventures that I'm running. That's plenty good enough for my kids as they learn the system and I get more comfortable with running it.
(Of course, anyone who follows my blog knows that I'm interested in trying a Freeport 5E game someday, and that will involve a lot of conversion from previous editions. But for now, my answer stands.)
