Not sure why this keep coming up.
But face it, the choice was a marketing strategy by FFG
it allowed them time to work on Jedi which have been the thorn in the side to every SWRGP
and put out more books to make money.
I will give them credit for not making each core book a carbon copy of the last.
plus for the species they are following the "Species sell Books" model.
Its the path they chose so live with it or don't its not going to change so why fuss about it.
