“The Player's Companion extends the core rules by adding a series of new classes, the dwarven machinist and spelunker, the elven ranger, and some human classes - mystic (monk), shaman (druid), and priestess. I'll come out and say it though, the thing that got me fired up with the book-love was the extensive list of templates. (I think they claim there are 144 of them). An ACKS template is basically some pre-selected options that speeds up character generation and gives the character a bit of early flavor. ACKS supports the old school roll-and-go - it's got basic 3d6 in order for abilities and simple classes, like classic D&D. The templates take it the rest of the way, by adding a preconfigured set of starting equipment, starting money, and suggested proficiency selections.”

“I've been running this game for months now using an open world sandbox game, similar to Ben Robbins' West Marches game, and it's downright amazing. Love the comprehensive rules for everything economic and the B/X framework with layered extras, like proficiencies and special maneuvers (disarm, wrestling, etc.). If you're at all into D&D, I would check this out.”

“This is what a rationalised 21st century dungeoncrawling RPG can look like: enough old school aspects to appeal to grognards, but with enough mechanical crunch to appeal to new(er) school players. The systems maths is robust enough that it doesn't fall to pieces if you breathe on it, but simple enough that you only need to do simple-addition-up-to-20 in play. And we did it crowdfunded and with substantiative fan base interaction and customer feedback.”
