Then of course we have the modern marvels like touch screens, dual screens, funky 3D controls, rumblepaks, and gyroscopic infrared remotes. And they almost gave us the first good CD console (which Sega almost ruined for everyone, lol). But yeah, they have been a very gimmicky company for decades. And while Gamecube wasn't gimmicky per se, it was an avant garde design, which I can appreciate.
