No, it was definitely minecraft story. That's the reason the wording is the way it is (see how it perfectly fits the original minecraft story example), whereas with the portal story it doesn't fit at all. I think the name should actually be changed to minecraft story, since that's what it originally was. The portal story example was what kicked it off as a meme, though. nevermind
Also note that the post following the OP, by captain fabulous, is:
This is because minecraft story would be a lot like Terraria, a 2D minecraft-like game.
I remember this thread pretty well, probably because I was the one to lock it in the end.
