Back in 2015, ArenaNet held a launch party at its HQ during the hours leading up to the midnight launch of Guild Wars 2's first expansion Heart of Thorns that it live-streamed on Twitch. The employees there were celebrating in the back as the live-stream's host interviewed various people throughout the night. It was actually pretty fun to watch.
Will Zenimax have a similar launch party at its HQ leading up to a midnight launch of The Elder Scrolls Online's first expansion Morrowind this coming June, replete with a live-stream with various interviews and such?
