Here's something I didn't know until 10 minutes ago: Andy Weir, the author of The Martian, used to work for Blizzard. He actually worked on Warcraft II.
And he did not have a good time.
In an AMA on Reddit today Andy Weir was asked about his time at the studio.
I had a terrible time at Blizzard. The mid-1990s was a rough time to be a game programmer. The work hours were insane. I you were awake[sic], you were at work. I burned out.
Andy Weir worked at Blizzard long before it became the juggernaut it is today, but it is interesting that he had a difficult time at the studio. Speaking to people in the studio today, everyone seems so passionate and committed to their work. Blizzard has a 'ready when it's ready' mentality these days, so it is somewhat surprising to hear he had such a difficult time.
It is worth noting his comment though: "the mid-1990s was a rough time to be a game programmer". I'd like to hope times have changed a little. But developers still tend to talk about 'the crunch' with alarming regularity.
At least Andy Weir fell on his feet. The Martian just got the movie treatment and, from all accounts, it's pretty damn good!
