It is a sign that 343 Industries is LEARNING from their mistakes.
For a decade, they REFUSED to hire Halo fans or ex-Bungie devs (with the exception of Certain Affinity) and instead INTENTIONALLY hired people who either never played Halo or outrighted disliked Halo; all in the name of “we want new ideas and to no restrictions on creativity.”
That thinking is what got us Call of Halo 4: Generic Sci-Fi Warfare and Halo 5 Gorbians.
If 343 is allowing Bungie devs to return to the fold, then that means that they are FINALLY learning from mistakes that they have been repeating over and over for the past decade.
It isn’t much, but at least it is a good foot to start off on.
