Fortnite is a 2017 game. With that in mind, I think that the leading years would be 2017, 2013, and 2010.

But I'll go with 2017. It was the battle royale genre broke out in a big way leading to Fortnite becoming a cultural phenomenon the likes of which are rarely seen. The Switch's launch year was the best we've seen from any platform. Then you can add on Persona 5 as a cherry on top.
