Firs of all, thanks for taking the time to answer me!
I say this as someone with almost no experience with dice games, so take this with a grain of salt:
But I wonder if there would be much of a market for a Living Dice Game. The LCG model works because it's essentially just a variant of the very well established and popular CCG model. There are hundreds of CCGs out there (Board Game Geek lists 445 of them), and FFG has successfully marketed an alternative that keeps most of the major features of the CCG genre, but removes the randomized distribution and rarity. That's a huge selling point.
On the other hand, Collectable Dice Games are not a well established category. Board Game Geek lists only 15 CDGs. You would first have to find enough support for a dice game where you have to constantly keep buying new packs, which there just might not be, particularly considering that non-collectable dice games are already not that huge a market to begin with; whether or not those packs were randomized would be much less of a factor.
Well, of course I don't have enough information about the market to tell if a similar product could be profiting or not (I'm not involved in this kind of businesses at all…) but a market with no competitors may well be a good thing, after all!
Of course how sensible it could be to release such a product needs more investigation, which surely FFG can do.
In any case, a living dice game can be thought in several different ways, ranging from a quarriors-like game to a sort of miniature game, passing through a lot of other typologies.
A stroke of genius from the developers is probably needed to create a game whose longevity is high, is good to re-play, and that makes you want to buy expansions. In star trek the dice game, for instance, boosters introduced new ships with different stats, weapons, etc. A similar approach can create interest in the game.
But again, I'm not involved in such market at all, I'm surely missing a lot of aspect I don't even know I should take into consideration Luckily I'm not the one whose going to release a LDG, FFG is! (I hope. )
