What do you prefer then? Not too many options:
- Full game rulebook + separate Pamphlet for whatever minis are in the box
- Boxed game rulebook, rules for minis are in the same book
- Full game rulebook + expansion book(s)
How about this crazy idea:
Have two books in the box - one is just pure full core game rules (moving, shooting, dealing with vehicles), second just pure full rules, fluff, campaign for the two factions that are in the box.
This does a few things:
1) allows to release just full core rules separately, for anyone who doesn`t need/want models, but wants to have updated, errata`d, faq`ed full version of just core rules
2) New players get literally everything they need to start playing in one box, instead of some beta rules, after which they have to buy even more rules, isntead of say, something cooler like more models?
3) As more models (vehicles, new gangs) come out, they come out along with relevant rules (supplements) and everyone can happily buy what they need there and now, instead of having to buy books to "unlock" full content for the stuff they already bought earlier
What we have now is:
1) Cool big box with bunch of models, but only "beta" rules:
A) if I`m not interested in models, but want updated, errata`d, etc. rules, I`m shafted, because they are locked behind big box and I have to buy just the rules second hand on fb/ebay/whatever else 3rd party that is not gw
B) If I`m interested in everything, I`m still shafted and have to spend more money on another separate book, while still needing what is in the boxed book
C) If I`m a new player I have to spend a singificant amount of money on a box, which is great to start, but if I want to go deeper, I have to pay even more for another book, and if the box set didn`t get me hooked, well that`s a lot of cash spent and very little saving on not having the full rules already in the box (compared to if GW went with the crazy idea above)
