I would probably be pretty unpopular with all of the shareholders, but, here goes my take on things. I imagine the shareholders would revolt and would try to throw my arse out as I care about people way too damned much.
But, anyways, here we go.
First things first.
Immediately gather up the entire executive team and do an interview with them. Then immediately do an interview with all of their employees below them in their departments.
Anyone who is found to view video games to be viewed as nothing more than cereal boxes to be sold to satisfy shareholders, is immediately fired.
Anyone who is found to treat their employees like absolute shit or working them to death, or treating them with harassment, or sexual harassment, or sexist or denigrating comments, is also immediately fired.
Anyone who has been fired will be replaced by candidates that I have interviewed and selected as potential high priority replacements before hand.
Second step:
Gather up every single development team and it's leaders. Company wide meeting if necessary. Advise them that the culture of driving these people into the ground and destroying their lives is now over. True priority is on creativity and the health of the company's employees and their families. No one is allowed to work over 40 unless they clear it directly with their supervisory team, which will consist of going to at least 3 people in order to prevent one person from destroying the health and livelihood of their team. Constantly and consistently review who is working how many hours in order to ensure no one is destroying their health and home life.
Go to HR and immediately work on creating a much better and more powerful benefits package. Create a culture where people want to come to EA as it will be a place that cherishes and treasures it's people as it's true resource vs games being viewed as a frigging cereal box.
Third Step:
Immediately open the vault. Command and Conquer? It's getting a full new release by a team of individuals who truly love that game. Dungeon Keeper III? It's a thing now. It's getting done.
All of the beloved gems. All of the wonderful games that people remember. Those are getting worked on. In the meantime, speak with the development teams and listen to their creative ideas and pitches. Separate those ideas into AAA, AA, and A games. Let each one get released based on sussing out resources and how viable those ideas are by allowing a small team to create a demo to pitch the game.
Create separate teams accordingly to work on, and churn out those games. Also, plants vs zombies 2? Getting demonetized, immediately. Same goes for the other mobile games.
Fourth Step:
Set up a university that cycles devs in and out who want to teach, to give them a break if they so desire it. This way, tech and culture stays current for the students who are learning. Students who wish to and have the grades to prove it can immediately start at entry level positions at EA. Any ideas cultured through the university can be used as games with the full consent of the students and their agreements, with a copyright lawyer explaining to them in full their rights in the matter so that the students, wide eyed and wondrous as they are, don't get screwed over by a mega corporation.
And those are just some things to start. I could go on forever, but, yeah...like I said. I wouldn't be very popular with Shareholders.
