Pros
Committed to quality and value of the player experience. Over the past decade plus since Rockstar has been putting out games, they have mostly been synonymous with ultra high quality experiences. This still holds true for their flagship games. Legacy of the original culture that built the company is still quality at all costs. It's the 'at all costs' that limits the value of cultural aims for the company.
Cons
Poor process for replicating success on a consistent basis, which leads to a hurky jerky production process that is capable of only overly focusing on 1 title at a time, which leads to schedule and cost overruns on other projects in the portfolio. Initial efforts to centralize and leverage talent across all studios/games was a good idea, but as key middle and upper level people left the company, the ability to share focus diminished. New managers tend to be little more than mouth pieces.
