Ours was Spectre[0] as our school had a Macintosh lab. We learned to pick locks on that lab door, to sneak in and play the game together during lunch. Thankfully the lab teacher was an extremely passionate nerd like us, so was understanding, but it still involved a fair few lunchtime detentions over the year or two we did it.
