Advanced Song of Blade and Heroes (ASOBH) is the version of the rules that you found in Fightin’ Fungi so it is the same as basic SOBH but it adds:
1) reactions
2) special rules to simulate weapons and shields, e.g. Block, Long Reach, Flail, etc
3) a detailed spell system with 30+ spells

Supplements will add specific subsets of rules. For example, Hammer and Forge will add Runecasting, some weapons, and a few more wall spells. Leaf and Arrow (Elves) will add different types of bows and special Arrows. And so on.

Each supplement is a larger full color book (which takes a lot of time to illustrate and pageset) so they will retail for around $10 but be around $8 in the kickstarter and in some pledge tiers it will just be bundled with figures.

Standard SOBH will continue to be printed and supported. It is not outdated: it is just a bit less detailed.

Each ASOBH book will add hundreds of profiles. Special rules are called Traits in ASOBH. The point system is the same. Advancement rules are narrative based in ASOBH. Alternatively, use SDG.

ASOBH books will be self contained. Meaning that with that book and ASOBH you can play without needing any other book. You have profiles, factions, all special rules needed for the profiles, a setting and simple advancement rules. In the case of Fightin’ Fungi, the ASOBH rules are in the Fightin’ Fungi book so you do not need to buy ASOBH.

All ASOBH books ideally come with their own range of miniatures and a map of a small area of the ASOBH world, also used as a location for Tales of Blades and Heroes rpg products.

The background is designed to let you play any figures you already have with minimum hassle. It is deliberately left vague so you can weave your own narrative in the world without “breaking” anything. Use of the game world is optional.

It is a highly magical, high fantasy world where competing gods created competing races. We will have classic races (orcs, elves, etc) but also unusual ones (fungi folk, mothmen). We will also do large monsters and steampunk/clockwork cultures, fey creatures and so on. It is a varied setting and there is an in-background reason for this “menagerie of cultures” approach.

The world will be revealed one little step at a time. When we have enough maps, we will put them together and release a large continent map. All will lead to a big war campaign when we have Armies and Hordes. But this will take years.

We have two professional fiction writers on board to write novellas set in the game world. Appendices in the novellas will “start up” any spell, monster or character used in the story. We will use kickstarter to gauge interest in these products. Novellas will be available in pdf, mobi, epub and paperback.

Is this enough?
