The guild crests won't have any impact on the game unless you choose to use them when you start your adventure. I don't see how this will impact the game's focus.

I've backed for the poster + trilogy because I think this type of game offers something quite different than other games out there. In a way, it seems like a choose-your-own-adventure type of story only with many, many, more variances than a book could ever have. Also, I'm sure you have to add in a dose of randomness as the same choices may not lead to the same results every time around.
