So all those DS and 3DS users, and the GBA users before. Those were all fake too?
Your graph fails to address the fact that N64, Gamecube, and Wii U all happen to be Nintendo’s poorer consoles, rife with problems, and lousy lineups. While the N64 had a few compelling games (Mario 64, GE 007, and Ocarina) it had few other games to go with it. The Gamecube and Wii U were both devoid of killer apps. N64 also suffered from extraordinarily high game prices, and a severe lack of selection (also a problem on Gamecube and Wii U which suffered massive droughts). The Wii has a compelling price point and new interface, and software was plentiful from launch: with Zelda Twilight Princess, Wii Sports, Metroid Prime 3, Fire Emblem, Super Paper Mario, Godfather, Scarface, Resident Evil 4, Wii Fit, Guitar Hero, Umbrella Chronicles, Tiger Woods Golf, No More Heroes, Wario Ware Smooth Moves, Sonic, Sims, Virtual Console, Simpsons, Spyro, PES, Tomb Raider, DDR, Fifa, Endless Ocean, NiGHTS, Trauma Center, SSX, Call of Duty, Medal of Honour, Far Cry, Red Steel, Bully, Rayman, Need for Speed, and Okami all releasing in the first year. That first year is already stronger than Gamecube’s lifetime.
While it is true that Wii did attract a lot of women to the console, so has Switch, and in roughly the same ratios as the Wii.
Even if the primary age group happened to be children (teenagers were actually the largest demographic) that would have also been true with NES and SNES, are those fake sales too? 920 million pieces of software sold, the highest of any Nintendo console, was that fake too?
