Pros
Studio atmosphere is fun. Strong concentration of talent at the team level. Great supporting and operational staff in the studios.
Cons
Communication between studios and corporate in SF is abysmal. A breakdown between the C-Suite level and the studio leadership can doom projects and the jobs of the people working on them. Performance standards are uneven between studios and making it very clear which titles are the pet projects. It's worth also looking at their insane commitment to celebrity titles - they're known as the company that developed the highly successful Kim Kardashian game. Since the success of that title, they have invested their entire future into celebrity titles. However, since the success of KKH, not a single one of their celebrity deals has actually translated into financial success and this is probably because "# of followers on Facebook" isn't a key indicator for success... and they might have known this if their market research and data analytics weren't in the stone age. Finally, it's worth mentioning the huge data breach where pretty much everyone who worked for Glu in 2015 had their W-2s uploaded to an external website. It's hard to pick which of Glu's many failings to attribute this blunder to, so I'll leave it to the imagination.
