* ApprovalOfGod: Series creator Creator/HideoKojima has mixed feelings about the game, but on the whole he clearly has a higher opinion of it than the Platform/NintendoEntertainmentSystem port of [[VideoGame/MetalGear1 the first game]]. He once jokingly called it a "crappy game", but in his more serious statements, he has said that he doesn't think that it was a bad game at all and even called it "faithful to the Metal Gear concept".
* ExecutiveMeddling: A positive example. A member of the ''Snake's Revenge'' team approached Kojima during a train ride and suggested he make a true sequel of ''Metal Gear''.
* FanTranslation: As the only ''VideoGame/MetalGear'' game to never receive an official Japanese release, Makimura Manufacturing took it upon themselves to release an [[http://www.romhacking.net/translations/2506/ unofficial Japanese translation]] of ''Snake's Revenge'' in 2010.
* KeepCirculatingTheTapes: Much like the NES version of the original game, ''Snake's Revenge'' never got a re-release until 2023's ''[[CompilationRerelease Metal Gear Solid Master Collection Vol. 1]]'', not even as a bonus for certain versions of ''The Twin Snakes''.
* LateExportForYou: It is included in the 2023 release of ''Metal Gear Solid: Master Collection Vol. 1'', marking the game's debut in Japan, 33 years after it originally came out in North America. However, this release [[NoDubForYou only contains the English script]].
* OvertookTheManga: ''Snake's Revenge'' was made before Kojima developed his own [=MSX2=] sequel and takes the game's plot into a different direction that makes both games irreconcilable with each other.
* WhatCouldHaveBeen: There are a number of ways the series could have gone after this game, all things considered. Imagine if the game wasn't rendered CanonDiscontinuity; how would games like ''VideoGame/MetalGearSolid'' have continued its events?
