I've no idea how the Portal sold so well. The entire point of a console gaming was to play games in a lounge setting on a 4k bigboy TV. Unless you have kids you need to offload to watch the rugby, what's the point!
For the past 20 years, console gaming has seen me sat at a desk in front of a 27" monitor - I could never do anything competitive (online) sitting on a couch in front of a massive TV. I used the portal for what you just described!
