Blizzard har formet deres store spilunivers via hårdt arbejde fra en stab af kreative manuskriptforfattere og designere, som har arbejdet for studiet i mange, mange år. Men i løbet af de sidste par år er mange af disse faldet fra, og nu har Blizzard mistet endnu en af deres kerneansatte.
Vi taler her om Michael Chu, der har siddet som hovedmanuskriptforfatter på blandt andet Overwatch. Han har også været med til at forme Warcraft-universet, samt skrevet lore til Diablo. Alt i alt har han arbejdet for Blizzard i over 20 år. I et blogindlæg skriver han følgende:
"From the battles between the races of Azeroth in Warcraft to the corruption of humanity as pawns of the Eternal Conflict in Diablo, I was lucky enough to tell stories in these amazing universes and help bring them to life. And I have had the great fortune to get to know and interact with the passionate global community that played our games. Now, as I head out through the Blizzard doors for a last time, I have new dreams: to continue to tell these stories and build worlds that unite people through games. To help create an inclusive world where more people will want to share stories that reflect their own experiences. I hope it's something we can build together."
