Only Razer is pulling the mandatory online signup thing. My keyboard (a "durgod" mechanical) and mouse (Zowie brand) are geared towards gamers, high quality, and need 0 software config - there's a lone DPI adjustment button on the underside of the mouse. "Gaming" monitors and graphics cards are also quite nice.

When it comes to RGB crap and gamer audio gear or gamer chairs, yeah, it's all pure-gimmick rubbish.
