How does Retro City Rampage get so many jokes in at once while remaining a playable game? This latest trailer, for example, introduces "Biffman," a superhero for whom your character substitutes.
In just a few brief scenes (and relatively few pixels!) this setup allows Vblank to make fun of Batman in general, and the '60s TV show in specific, while making a random, but logically sound, Pitfall! reference -- and a related Atari 2600 joke.
"Biffman" is also a funny name, on its own.
