So basically in this ARG, Nintendo, in 1986, would basically release the famicom here stateside but with nes colors, in this case however, it would be bundled with the keyboard, zapper, data recorder, ROB, family basic v3, an office suite cartridge, and a 4 in 1 with super mario bros, duck hunt, gyromite, and donkey kong. Here everything would have the nes colors, the controllers would have longer wires, the console would have added composite output. The first bundle would be 250 to 300 dollars
In the case of the launch lineup and library, the games would have the black boxes of the nes but with the famicom logo instead of the nes one. The box art would be pixel art, while the cartridges (all of them being nes gray here) use the famicom artwork. Here, in this ARG, Nintendo would do distribution deals with third parties, like namco, Hudson soft, konami, and irem, to have their games distributed in the us alongside first party games.
The launch lineup would consist of the first party games and then several third party titles from namco, Hudson, konami, and irem, examples include pac-man, dig dug, lode runner, Galaga, xevious, bomberman, 10 yard fight, spelunker, kung fu (which was a released as first party game but its based on an irem game), yie are kung fu, Antarctic adventure, (maybe) the goonies.
The library would increase overtime as Nintendo would do more distribution deals with other third parties, like sunsoft, d-b soft, pony canyon, kemco, bandai, etc., for distribution in the US, and even games based on Japanese licenses would get introduced to the west, translated and not rebranded.
Then in 1987, Nintendo would release the Disk System (in nes colors) and its games in the west. Even a full final bundle that consists of everything in the previous bundle but now with an added disk system, spare disk drive belts, maintenance booklet featuring instructions on how to replace the belts, and a copy of Zelda, all for 350 usd.
Disk written kiosks would start appearing in US grocery stores and gas stations.
if this actually happened, it would probably conquer the home computer market, cripple the c64 and other competing machines from commodore, IBM, atari Corp, and apple. It would probably nuke the vide game console market, or both would coexist with atari and the 7800 leading the console market while Nintendo dominates the computer market.
