I confess to that contest being personally inspired by the alternate world of Edolas from the anime Fairy Tail.  In that case, it was an entire story arc rather than a single episode.

Oh, and I'll have the new contest up soon.  This will be an interesting one I hope.

My entree was based on the Stargate Episode Moebius, where they went back in time with the intent of making things better but it spiraled out of control creating a world unprepared for what it would face.

Fairy Tail for the win!
