BB2016 came with 'boxed' rulebook, limited & cropped rules to cover only the basics included in the box. BB2020 included a full rulebook covering pretty much the entire game (at that point at least). That's a proper rulebook, similar to how kill team rulebook is or other games blessed with rulebooks covering the game instead of the boxed content.I think the precedent here may be the recent Blood Bowl boxed games. If I remember correctly both Dungeon Bowl and the updated boxed game come with hardbacks. I'm hoping that also means the rulebook will be sold outside the box.
I'm confident the Ash Wastes rulebook will be mostly limited to the boxed content, as all previous Necromunda rulebooks have (more or less):
- N17 rulebook: Strictly boxed content (only Goliath & Escher, no campaign, no 3d terrain rules, different game system than the full game)
- N18 rulebook: Full rulebook for the full game (separate from any box).
- N19 rulebook: Mixed, most universal rules, otherwise covering rules for the boxed content only (for example no psychic power rules because there are no psychers in the box).
- N21 rulebook: Mixed, most universal rules, also simplified rules for all house gangs (no campaign, no psychic power rules, no universal skill system, different game system than the full game).
