Okay, so this is where things get confusing and we’re only on fourteen! Metal Gear was developed for the Japanese MSX2 computer. That game was then ported to the NES albeit at a downgraded version. Following this was two sequels. Snake’s Revenge was developed exclusively for North American and European
territories, never coming to Japan in any form, while the actual sequel, Metal Gear 2: Solid Snake, released on the MSX2 as well. Admittedly, I have not beaten this game since it’s pretty hard even for a NES game and I just have no interest in it, since Kojima wasn’t involved and it’s in a weird other timeline of sorts. Nothing is really wrong with it, but it just lacks a magic touch. Everything feels less polished basically.
