Pros
For the better part of a decade I've been working at Blizzard HQ in Irvine. In all that time I've never met a fellow employee who wasn't interesting, upbeat, and utterly driven by what they do for a living. The work can be challenging no doubt, but that's part of the attraction to me - building things that we can't build on our own, and being a part of something that entertains and enriches so many. The culture is organic and evolves, and the pride of craftsmanship is evident everywhere on campus. Great perks, fantastic benefits, and they work hard to keep their talent!
Cons
I've worked in several different industries before gaming, and I've never seen the amount of collaboration that I do here - if you're not into knowledge-sharing and working with a lot of stakeholders, the culture might not be to your liking or work style.
