In Sonic the Hedgehog in the Fourth Dimension (1993), the progressive rock band King Crimson’s 1973 album Larks’ Tongues in Aspic is referenced by name.
The 2016 multiplatform game Hitman contains a reference to Mario and Luigi as two NPCs in the Sapienza level, who are plumbers with red and green clothing working in the sewers and are named Mario Saltatore and Luigi Saltatore. “Saltatore” translates to “jumper”, further referencing the Mario series. An optonal challenge presented to the player is killing either of them while wearing the other one’s clothes.
