There is a unified pricing system - so, for example, EarthBound would cost the same price as F-Zero - however, games are incredibly cheap. Given how easy splurging could be, Switch System Settings would let you choose between having each VC game be a single app or their own slot on the menu. Nintendo's arcade titles would still be distributed through Hamster's Arcade Archives.
NES/Game Boy/Game Boy Colour: £2.99
SNES/GBA: £3.99
N64/DS: £6.99
GameCube: £9.99
Nintendo's games would not be drip fed but rather all of them would be avaliable from day one bar copyright issues (though attempts would be made to get those games), while third party titles would be added periodically
If an accessory or gimmick is possible (and comfortable) to support, it'll be supported. Sorry Boktai. Gimmicky games usually aren't part of the bundles mentioned below, but there are exceptions.
Each Switch would come bundled with 11 retro games, determined by the colour of the Joy-Cons bundled with the console bought - all except one (Tetris (GB)) are first party, Tetris is also a constant between all game lists with the rest being 2 NES, 2 SNES, 2 GB, 2 GBA, 2 N64. The pre-loaded games can be deleted to save space and redownloaded. Bundled games can be bought from the eShop if they're not included with your style.
For colourful Joy-Cons (casual focus)
- Excitebike (NES)
- Kirby's Adventure (NES)
- Super Mario World (SNES)
- Donkey Kong Country (SNES)
- Game & Watch Gallery (GB)
- Mole Mania (GB)
- WarioWare Twisted! (GBA)
- Kuru Kuru Kururin (GBA)
- Pokémon Puzzle League (64)
- Mario Kart 64 (64)
for darker Joy-Cons (hardcore focus)
- Kid Icarus (NES)
- StarTropics (NES)
- Super Metroid (SNES)
- EarthBound (SNES)
- X (GB) (English!)
- Frog for Whom the Bell Tolls (GB) (English!)
- Golden Sun (GBA)
- Fire Emblem: The Sacred Stones (GBA)
- Ocarina of Time (64)
- Lylat Wars (64)
When you boot up your Switch for the first time, the order of the retro games displayed will be based on what profile icon you choose - for example, a Donkey Kong profile icon would prioritise DKC while a Kirby icon would prioritise Kirby's Adventure. However, Tetris will always come first regardless of icon or joy con colours. Other Switch variants may have different game lists, for example the Mario Odyssey set would come with these Mario games alongside Tetris
- Super Mario Bros. (NES)
- Super Mario Bros. 2 (NES)
- Super Mario World (SNES)
- Yoshi's Island (SNES)
- Super Mario Land (GB)
- Donkey Kong 94 (GB)
- Super Mario Advance 4: Super Mario Bros. 3 (GBA)
- Wario Land 4 (GBA)
- Super Mario 64 (64)
- Mario Kart 64 (64)
and the Fortnite set would have these games alongside Tetris, chosen to appeal to a Fortnite audience on either a thematic or mechanical level:
- Mach Rider (NES)
- Kid Icarus (NES)
- Tin Star (SNES)
- Super Metroid (SNES)
- X (GB) (English!)
- Solar Striker (GB)
- Advance Wars (GBA)
- Drill Dozer (GBA)
- Lylat Wars (64)
- Wave Race 64 (64)
Of course, the Smash Ultimate set would feature characters or stages in the game who's origins or importance may be foreign to younger gamers:
- Ice Climber (NES)
- Balloon Fight (NES)
- EarthBound (SNES)
- Donkey Kong Country 2 (SNES)
- Kid Icarus: Of Myths and Monsters (GB)
- Super Mario Land 3: Wario Land (GB)
- Metroid: Zero Mission (GBA)
- Game & Watch Gallery 4 (GBA)
- Super Smash Bros. (N64)
- F-Zero X (N64)
There would also be an officially licensed ROM dumper periphiral for the Switch, known as the "Game Transformer", allowing players to convert their old cartridges and discs into Switch titles.
Fan-made mods, if of a high enough quality, could be released as official titles with permission from and compensation towards their devs.
Jokes aside, I love your idea there... I'm just not sure how some people would feel about the free games they get being defined by the colours of Joy-Cons they buy. Otherwise, though? I a d o r e it.
