When does something become official?
When backed by a company that also produces miniature?
When the employers are being payed?
For all I know:
We have our own IP, meaning that anybody who want to earn a profit needs a written permission from one of the ExB members.
We're supported by Shieldwolf miniatures, although naturally to a limited extend.
We're one of the systems to be played by ETC.
When does something become official?... certainly not when it carries the label "fan made". There can be a multitude of factors that contribute or detract from the officiality of a product/entity. However at the heart of it, I feel it comes down to the original authorship. In this case, GW (precisely employees employed by GW and hence "GW") created the game of Warhammer, while 9th Age took that creation and merely tweaked it. I would liken T9A to something like fan fiction. You can write a story about Harry Potter for instance (and it might very well be amazing), but the
official cannon would restricted to the material released by J.K. Rowling.
In terms of T9A, the IP you mentioned would be the official IP for T9A, which is turn is an "unofficial" version of Warhammer. Having the support of Shieldwolf miniatures is a good start, though as you admit it is only to a limited extent. It in no way compares to the model support that GW provides its games, both in scope and in focus. GW had models for just about every unit + character in the game (with a few exceptions). Also Shieldwolf miniatures and T9A are not a single entity, so it opens up the possibility of differing ideas, motivations and directions. In any case it is not a unified and complete product as that released by GW.
Saying that "T9A would die of GW did X" is useless. What's the purpose?
I beg to differ. Its purpose was to emphasize my counter argument to KillerK's stance of "The thing is, T9A project is getting support from multiple companies, and it has a tendency to grow. It's something that GW can never ever match." Not only do I feel that GW could match T9A, but it could outright kill it if it so desired (or even inadvertently).
Right now GW is doing their AoS thing and thats basically it and they're not going to relaunch with a WHFB 9th. Anybody who's foolishly holding out for that are tricking themselves.
Which I actually clearly stated in my original post... "Of course GW is not releasing 9th edition, so it will be interesting to see how T9A can flourish in the void left behind by Warhammer's demise". I never expressed an intention of holding out for 9th edition, I was supporting my counterargument to KillerK's original statement by pointing out that the hypothetical release of 9th would destroy T9A.
To simplify, KillerK was basically arguing that T9A > GW/Warhammer. My argument is that not only is that untrue, but in reality T9A < GW/Warhammer. I'd go even as far as stating that...
Warhammer 8th (in its prime) > current ( AoS + KoW + T9A)
What will happen in the future... who knows? Though if I was a betting man I would wager that T9A never eclipses the levels that Warhammer achieved (in terms of community and popularity). I won't argue which game is better because that is quite subjective. You would choose T9A and I would choose 8th edition.
None of this is to say that a fan made game can not be great and successful. The continuation of Blood Bowl is a prime example how a fan maintained set of rules can survive and flourish for so long. It will be interesting to see what happens when GW re-releases the official product though.
