I knew someone would argue this. But I'm not talking about in terms of sales.
I'm talking about, when the Gamecube came out, the Big Four upcoming releases were Mario, Metroid, Zelda, and Smash
And when the Wii came out, the Big Four upcoming releases were Mario, Metroid, Zelda, and Smash.
And I would bet money that when we get a real, full Wii U reveal, you know what the highlights are probably gonna be? Mario, Metroid, Zelda, and Smash.
Mario, Metroid, Zelda, and Smash are the four franchises Nintendo goes to when they want to show something off. Kirby and Pokemon probably sell better than Metroid (hell, Pokemon probably sells better than Zelda), but Kirby usually comes later in the game, and Pokemon kinda does its own thing on handhelds.
