Conan Exiles PS4 Question

#1

is the upcoming retail boxed PS4 physical disc version of Conan Exiles worth Pre Odering from GameStop?!

#2

Well I heard it has offline single player option, so it seems like its worth owning physically rather than digital.
not sure if it comes with an instruction guide with pages.

#3

I also think you will get a extra sword or something. Not sure about this
