Creator Shinji Mikami promised in an interview that if Resident Evil 4 were to appear on any platform other than GameCube, he would self-decapitate his head. The game has since appeared on PS2, Windows, Wii, iOS, Zeebo, PS3, Xbox 360, Android, PS4, Xbox One, and Switch. At the time of writing, Mikami’s head is still intact.
Resident Evil 4 pioneered an excellent shooting system as its main contribution. It would mark a shift in tone and style for the series, and go on to have Doom II levels of audience reach. A calculator port is only a matter of time.
