Apart from the DLC heroes, yes.
This was all fiction I wrote in my spare time. After work, on the weekends. I did it to help share the background I'd developed for the Evolve Universe with the rest of the team.
I shared them with you guys because I thought you might dig it.
My day job though is writing the thousands and thousands of lines of battle chatter and banter. We only got one writer, it's a lot of work.
That's not up to me, it's up to the guys who design the UI and unlockables, but in general I'm against it. I think reading large blocks of text in video games is an extremely poor experience and one the medium is badly suited for.
Comics or even like, radio plays of this stuff would be better. But, again, that's not up to me.
I don't see "there are people who play the game who don't know this stuff!" as a problem. To me, it's fine. The game is a complete experience, you don't need this stuff to have a good time or understand it.
