295 - Insurgent
A very quick little modern game designed to be played solo or with a small group but no GM, in which you rebel against something. What do you rebel against? Whattaya got? Learn more about your ad choices. Visit megaphone.fm/adchoices

294 - OGL Ancients
It's what it says! Though it's adding a lot of stuff to the venerable old combat engine of 3.X OGL, it's an OGL game where you play as primarily Greeks and Egyptians from antiquity (you can get a Scythian or someone from Thessaly in if you want, it's just not a great plan).

293 - Alas Vegas
This is a little recent for our usual stuff, but Jon was really interested after the Fastlane review to keep looking at games that utilize classic casino games as RPG randomizers, and this one's a doozy! Combining Blackjack and Tarot stuff, no less! Right in Jon's very wheelhouse. The game is neat too! There's a ton in here, it's definitely one of those big rocks that rolled down a Kickstarter success story and accumulated content as it went, so we made some calls on what to focus on that we'll explain within. At the end of the day, this is pretty dang neat. Learn more about your ad choices. Visit megaphone.fm/adchoices

292 - Unbidden
Back to basics, some game you probably never heard of that we didn't like. That's the basic essence of the show, right? It has to come up sometimes. I'm talking about the show here because honestly I can't think of much to say about this sort of generic "There are secrets in the world that you can't learn about without going crazy" type game that isn't already in the episode.

291 - Fastlane
Oh buddy you better believe we love it when the game has a weird alternative randomizing mechanic, and this thing is all about roulette. Yes, it straight up tells you at the start that you can use a digital one or even a dice based approximation, but for max results, you should get a roulette wheel. What else? Well, it's a generic system besides the ruleset, so we go all in on that. Learn more about your ad choices. Visit megaphone.fm/adchoices

290 - Icarus
As we bring Sweater Weather to a close we are faced with the realization that we accidentally double-themed this month, since both of these games are explorations of civilizations over time, and in fact would make a pretty good double feature game night played together. Weird! Anyway, this is a little box set where you make a dice tower. Learn more about your ad choices. Visit megaphone.fm/adchoices

289 - The Quiet Year
Hey folks, welcome to Sweater Weather. We're going to keep things light and distracting here for the next few months, sweater weather or not, so don't worry about heavy topics. If you're looking for a getaway, we got you. Also, this book is about impending change and possible doom. So. You know, we'll figure it out. Learn more about your ad choices.

288 - Rats!
So these aren't really furries, but hey, I think this was just called Hairy Ween, right? Like that sounds more like a dick joke anyway. Anyhow, this book is all about playing as vile, disgusting, brilliant little rats trying to retake the world from the foul humans that don't deserve it. It's a mixed bag!

287 - Mutants in the Now
Blessed Ween everyone! This year we're focusing on animal inside of us all with a Furry Ween! Or a Hairy Ween! I dunno, whatever, we just wanted to read Mutants in the Now. Learn more about your ad choices. Visit megaphone.fm/adchoices

286 - Orkworld (Crunch)
Oh, oh no. We thought all the worst stuff was going to be in the fluff and descriptive section. We were wrong. If you're a fan of angry Jef and Jon, well, you probably already noticed the 84 minute runtime of the episode and got your hopes up, correctly. Learn more about your ad choices.
