The Riddler does eventually escape the virtual reality program, though it is not explain how and gets arrested afterwards as his next episode Riddler's Reform (1994) depicts him as being released on parole.
The Riddler does almost exactly the same thing he did in the episode If You're So Smart, Why Aren't You Rich? (1992) by trapping someone in a specialized game where Batman must solve numerous puzzles to save the captives Daniel Mockridge /Commissioner Gordon.
The chessboard stage of the virtual reality world was adapted into the second stage of the Riddler level in the Super Nintendo game The Adventures of Batman & Robin (1994).
The look of Nygma's virtual world was inspired by the works of famous surrealist painters. The staircases Gordon and Robin walked on was a trademark of M.C. Escher, the train emerging from the fireplace was a homage to René Magritte's Time Transfixed, and the place where Nygma and Batman had their final confrontation was a nod to the paintings of Giorgio De Chirico.
The idea of the Riddler leaving behind a numeric pattern hidden in the questions of past riddles was later used in the feature film Batman Forever (1995).
