Same story with Nintendo, they've been milking Mario, Zelda, and Pokemon for the past few years with the occasional Kirby and Metroid game, with barely any of their other franchises getting love.
You do have a point there, but it's not as simple as that. First off, Nintendo's Big 3 varies throughout the platforms. Here's my opinion on them:
NES Big Three:
Super Mario Bros, The Legend of Zelda, Metroid
Game Boy Big Three:
Super Mario Bros, The Legend of Zelda, Kirby
SNES Big Three:
Super Mario Bros, The Legend of Zelda, Kirby
N64 Big Three:
Super Mario Bros, The Legend of Zelda, Donkey Kong
Game Boy Color Big Three:
Super Mario Bros, The Legend of Zelda, Pokemon
Game Boy Advance Big Three:
Super Mario Bros, The Legend of Zelda, Pokemon
Gamecube Big Three:
Super Mario Bros, The Legend of Zelda, Star Fox
Nintendo DS Big Three:
Super Mario Bros, The Legend of Zelda, Pokemon
Wii Big Three:
Super Mario Bros, The Legend of Zelda, Mii's
Super Mario Bros and The Legend of Zelda have remained stable throughout the year, but the third one has been changing a lot over the past twenty-five years or so, consisting of numerous franchises. If the Internet existed during the SNES era, you would be complaining about Kirby being overrepresented.
The only Nintendo franchise I can honestly say have been neglected is Earthbound, but let's not get to that. Star Fox has received at least one console entry since the SNES and even received an DS entry in 2005. F-Zero same case, only that they got a couple of GBA games too and no DS games (Not sure why, but that's a story for another day). Pokemon console games have received decent supports. Pikimin has two on Gamecube and will be getting another one. Not to mention of revivals of old series such as Excitebike, Punch-Out!!, and Sin & Punishment on the Wii. On top of that, Nintendo has been pretty good with Fire Emblem.
Even thought The Legend of Zelda have always been part of the Big Three, but only recently have they received a decent number of games. When separating the console games and handheld games from each other, new Zelda games used to be an one per generation event, just like the Super Smash Bros. series is today.
What I will agree on is that Mario and Pokemon has been way overrepresented. It's been that way before with Mario, but it would be nice if Nintendo placed emphases on other franchises and gave both of them a rest, or at least noticeably cut the amount of games they put out for both franchises. I say Mii's or Kirby should be Nintendo's next mascot if that were to happen until a revival of Mario games.
As for Pokémon, it needs to die in general. The franchise has declined all-around in quality and I have lost hope in the franchise gaining back my attention for future installments. I might get past games once I get another GBA and GBC, but not upcoming Pokémon games. I've been brunt on every single Pokémon game since 2004 (
Pokémon Diamond and Pearl was decent, but I was still very disappointed with the game).
