we had a member of my team at a company about ~15years ago that they tried to fire for installing steam on their corporate laptop when they had sent him to another city for for what was supposed to be a week but ended up being three weeks. this was against our wishes (he didn't need to be there, there was no good reason for it, he could do all the work remotely from our office and had been doing it successfully for three months, the project was 'at risk' due to schedules but none of that was our fault at all).

I had a knockdown drag out fight with both HR and Security. I agree that it was probably better for him to have packed his own personal laptop or similar gaming device but security had shown absolutely no risk and it was clear that HR was just 'clucking to cluck'. Eventually they relented with a mealy mouthed 'warning'. The fact that he had installed steam after his stay had been extended and they couldn't show any evidence that he was playing during working hours was a hillarious, and lucky, footnote.

Time to bring back the Boss Button https://en.wikipedia.org/wiki/Boss_button :)

Then its time to break out the good old MUDs

True story:

I was working in the Techstop (40) @ Google, 2011-ish, when a nice person from PeopleOps came through and politely requested my admin powers to help them install Steam on their corp-issued Windows laptop.

I'm sorry, what?

Well see, PeopleOps was going to have an onsite intending to help recruiters better understand Engineering types, and part of the whole business was going to involve everyone firing up a copy of Portal and playing a puzzle-solving video game.

So I immediately got to it. Never heard back as to the success of the endeavor, but turns out there are circumstances where you can break out your Steam library at work.

Coward! /s
