Consider Contra's 99 lives cheat code vs candy crush's extra lives for cold hard cash.
Though by far the most popular is a version of starcraft's instant build cheat coupled with a persistent RTS game.
As to traditional cheat codes, there more common in RPG's. Skyrim console being a great example of a classic cheat codes.
Was Sega not very big in the US in that era? Most of the old gaming references I see online are NES-based (or at least Nintendo), but the first cheat code I learned was Up, Down, Left, Right, A+Start.
Sega was pretty much unknown in the US until the Genesis came out, and never really beat Nintendo in popularity.

popularized among North American players in the NES version of Contra, for which it was also dubbed both the "Contra Code" and "30 Lives Code"
