Having worked in/with sysadmins in a corporate environment, one of my strongest reasons for pushing Unix or Macs to the desktop was to prevent the use of PC’s for games.
Macs and Linux both have games. But Windows probably has more manageable software to control that in the environment (now). So when was that 1995? Not mocking you but just wondering.
Also who cares...there are games galore online now, so if you’re really worried about that you might as well pull the internet plug from them as well. And there are games that can be played via email or IM so you better pull that too. I work with extremely large enterprises everyday. In fact, I’d say I’m responsible for one of the largest networks in the world. Windows allows us to lock down the desktop quite nicely (now).
