A Games console does not require different video configurations, but some prefer different settings on their TVs than what they'd otherwise use while they play games. Most TVs have a games mode anyway that will override the TVs conventional settings when engaged. Some games consoles can also be used as Blu-ray or even UHD players and you'd not be able to convey the HD audio associated with these discs via S/PDIF optical. Such formats require a direct HDMI connection from the console to the receiver.
