The Calgary gaming convention Underground Con is on June 9th, 2012. K-Slacker who is a friend of mine, attended last year and had nothing but good things to say.
I have signed up to DM Castle of the Mad Archmage using OD&D.
K-Slacker is GMing a game of Tempora Mutantur:
By KBR. The Fall has long since wiped out civilization, leaving the planet's surface a savage land of radioactive waste crawling with mutant creatures, and forcing the few survivors underground. Your community has endured through the long years since the Fall, its inhabitants sheltered safely beneath the earth. Until now…
'Scavengers' they call you. You and the other volunteers are being sent above ground to salvage whatever you can from the ashes. Armed only with your wits and the weapons you find, you must travel through this less-than-inviting real estate on the surface.
Stay alert! Fierce radiation storms can blow up at any time, causing all kinds of nasty mutations. And hordes of marauding monsters are roaming around just waiting to make you the snack du jour.
Few have made the journey, and even fewer have survived. Can you?
Tempora Mutantur is a minimalist rules-light post-apocalyptic RPG. Pre-Gens will be provided! You can learn more about it at: http://tempora-mutantur-rpg.blogspot.com.
