In gaming, there are entire genres which expect people to cooperate to get better results. Initially, they don't know anything about each other, but in functional groups there's at least a silent agreement to work together and not cause a fuss. Let's say in professional environments, it's fair to expect most employed people would do the same (ergo, the hiring process properly filtered the problem people out).

Eventually people end up working together on things more and more. From there, depending on their personalities, they will either learn more about each other, or come to an agreement they are only there to do the work. Both outcomes are fair, though individuals might feel left out when their expectations aren't met (team culture mismatch).

By introducing these events, it feels like managers are trying to fastforward a process which would happen naturally, through events which have little to do with the work at hand. If your projects need collaboration, surely these people will eventually communicate with one another and go through the flow illustrated above. I only expect managers to step in when there's a clear mismatch or sign of dysfunction within the team.

And honestly, I'm skeptical whether functional adults as a whole enjoy the attempts at fastforwarding the process. These events have a tendency to feel forced and infantilizing.

I certainly don't. I'm there to make money, not friends.

I've tried making friends at work before, and it was never worth it. They expect you to be there for them, they're never there for you, and once you've left the company you might as well have never existed to them.
