So, I was probably 12 when I played Wasteland. One afternoon, I'd been wandering around in some dungeon...I believe it was a sewer, but this was too long ago to remember specifics. The next day at school, I was talking to a friend that was playing Wasteland as well. Kid named Tommy Nguyen. I told him about the sewer where I'd wandered around for a while and (presumably) died before I called it a day.
So he grabs a piece of paper and a pen, and starts drawing a little map. As he's drawing, he's telling me "Let's see, you fight a [something or other] here....and here's some [ammo or something, I don't really recall]..." And before long, he's drawn a complete map.
So I take it home that afternoon, head back into the sewer, map in hand....and the map that he'd drawn, off the cuff, was spot-on. Every square, every encounter. It was the damndest thing, especially since I'd watched him draw it, there in the classroom at school.
Anyhow, that's somehow become my most prominent memory of the game.
