While the article is just rubbish, as if vertical va horizontal is settled by sticking your games to the wall (how big do they think my house is, maybe if I life in a climbing gym). However for a few games it could be cool.
This is great if you are into avante garde displays but for us practical folks it’s just as easy to store games on a shelf and they still look pretty nice.
It will cost you about $150 for three games on the wall. Way too pricey and not worth the end result. Having a thick game jutting off the wall would look strange in many cases.
