Ain't that the case that when a company grows, the culture gets booted out the window and stomped into the ground. Play Nice, the recent book by Jason Scheier catalogued the same at Blizzard. Seen it myself at a company I worked at; it was at it's best at around 80 people when I joined, but steadily went downhill from there.
I've worked at a company that grew from about 15 people to over 30 while I was there. When I started we'd all have lunch at one big table and everyone knew what everyone else was doing, but at some point that just wasn't feasible any more. We also got middle managers and the entire thing suddenly felt a lot more like I was just a cog in the machine.
However, I don't think this was just a problem with the company growing. I'm currently working at an international company with thousands of employees, with the branch in my country having about 250 employees, though my team only has 3 people in it, plus my manager. The biggest difference however is that we get a lot of freedom in how we approach a problem. You feel a lot less like just a cog in the machine if you have more agency.
That's all rather depressing. They need to create something like a creative team (think modders) that works separate from the main team and can add all sorts of interesting things to a game.
Every team that creates something in game development is a creative team and should get the opportunity to work on their own things. Everyone should have at least one afternoon every week to work on things that aren't scheduled by someone else.
