Oh, really? What "innovation" is that? The jiggling breasts in DOA Extreme Beach Volleyball?
No, more like the action-adventure of Ninja Gaiden, the presentation of Viewtiful Joe, the original, new worlds of Skies of Arcadia and Baten Kaitos, the perfection and simulation of Gran Turismo 4, the immersion and pacing of Metal Gear Solid, the teamwork and narrative of Final Fantasy Tactics (Advance) and every single Nippon Ichi game ever made, the epic Xenosaga, a little game called GTA: San Andreas, and then the perennials like Mega Man, Metroid, Dragon Quest, Final Fantasy, and Castlevania. And that's just gameplay. You could get into music and go as far back as the NES--who hasn't memorized the world 1-1 music from Super Mario Bros.? You could go to the early '90s and talk about the music wars between Streets of Rage and Final Fight. You can hit the PSone era for games like Einhander, or come to modern day for soundtracks such as the London Philharmonic Orchestra-performed Xenosaga.
Please drop the hate.
