Pros
You can bring your dog to work.
Cons
You can expect to work 12 to 15+ hours a day, Mon through Saturday. You get free meals, etc. but that's because they don't want you to leave the office. It's disorganized and chaotic, though they like to call it "moving at zynga speed". Game design is led by Product Managers (not game designers). Focus changes on a daily basis and you're expected to constantly change direction, yet keep to schedule - hence the working long hours, six days a week. There's is no work/life balance - everything revolves around the company. Quarterly bonuses were much lower than what was said in the interview. No vacation policy (they say you should take some when needed), yet people were denied vacation or asked to work while on vacation.
