Pros
It's hard to think of any reason to work for a sweat-shop.
Cons
Ok, so the list: When they fire people, they don't do it quietly, they send an e-mail to the entire company saying "so-and-so is no longer an employee of Blizzard Entertainment, as with all guests, please escort them at all times when on company property". You've gotta be kidding me! you think that boosts morale? what a joke. Regarding career development, I asked the lead game designer for WoW about what it would take for me to move from being a tools programmer to a game developer. My problem was I had no experience, and all job requirements say you need at least 2 shipped titles. Guess what his answer was!? He told me "to be quite honest, you'll probably have to leave Blizzard, get some experience else-where, then come back to work here". You've gotta be freakin' kidding me if you consider that career growth, and advancement opportunities.
