Campaign Mastery

Today, I offer a new technique for rolling multiple dice many times with great efficiency. Any RPG can benefit from that! I hope everyone had a wonderful Christmas break. Mine was great, though not without its challenges – but I have evidently weathered them, because here we all are, in a bright and shiny New […]

The AEE is a subsystem that slots into any RPG for simulating everything from Bad Weather to Plagues & Poisons. The Backstory A while back, I was working on an adventure for one my campaigns (being deliberately vague, here) and I needed to look up the effects of Cobra Venom in the Hero System. I […]

The likelihood of your home being robbed drops by a ratio of between 100-1000 times if you live […]

Not all RPG players and GMs are Geeks, it has to be said, but many of us can spend hours noodling over dice and probability curves and other Geeky dice-related subjects, […]
