What does the game selection have to do with the console itself though?
Like everything? It is what all that hardware is for, if it isnt giving me anything new then what is the point? The hardware improvements are marginal and not all that special in terms of a unique selling point.
And the conditions only explain the situation not excuse it, this generation is boring and did not progress the industry much. I think it is across all consoles, there was nothing special other than minor graphical improvements.
The industry also shat out remakes and remasters instead of new content.
