Fictorians: Long before Portal or Portal 2, there was MYST, played exclusively on the PC. I know Portal can be played in other formats. In fact, it’s probably preferable, but we never got around to graduating our Nintendo any higher than a Wii, so when my kids and I played Portal, it was like the old days, on our PC. Watching my son’s fingers pounce around on the little plastic keys brought back memories. As much as I love Portal, especially the cake song at the end, I think MYST was better. It had EVERYTHING, and I think that’s a bit of a writing lesson.
