Pros
You can sometimes play some amazing games, and have contact with studios that can work miracles. There is also a lounge where workers can go on breaks to eat and play video games. The area is also one of the best, with multiple restaurants to choose from within walking distance.
Cons
Activsion has great games, but a lot of people in charge don't seem like they should be. Most of the managers don't understand their own jobs, and usually want you to take steps that are wholly unnecessary. Add in a constant nagging feeling that they'll never really want you to advance, and you will be in a frustrating and boring position. No matter how good your work ethic seems to be, from finding advanced bugs or taking on the jobs of QA leads. You won't be appreciated and constantly nagged over "small" things that seem odd during late game releases.
