Doom was, of course, originally released in 1993. It wasn’t until 1995 that it saw me get in trouble at school. We had fewer games then, and especially fewer games that could run on the crappy 486s that lined the edges of my sixth form (year 12, younglings) form room.
In the mid-90s, schools decided they needed computers. No one was quite sure what for, but they were needed. The Conservative government of the time encouraged it, and local councils would provide special funding for schools to invest in hundreds of beige boxes, so that there could be computers in every classroom. For which there was absolutely no purpose. The entire curriculum was written around text books and library resources, and the only software that was of any limited use was Encarta 95. Meanwhile, a History & Politics A Level class of twelve students was sharing textbooks one between three, because the school had no budget to buy more. Computers were being used as doorstops. It was very silly.
