“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.”
