I'm bored let's do something crazy :P
From this list of games that don't exist/won't exist or aren't coming out, which would sell the most.
- The Legend of Zelda: Dark Souls Directed by Christopher Nolan.
- Uncharted 5: The Last of Us
- Pokemon Mega Monsters Online
- Minecraft: Toaster Edition
- Luigi's Playboy Mansion
- The Last Guardian.
You might add your own fake game.
