One word to describe the PS4X1WU era and its Game of the Generation (GotG)

[Leadified]

There's been a lot of disappointments this gen (even from games which were good at the core like MGS V) but what exactly does "GotG" mean? A system defining title that also sold very well?

In the case of PS4 the first thing that comes to mind to me is Uncharted 4.
