Nier: Automata defeated Dujanah 14-3
Nioh defeated Pokemon Ultra Sun/Moon 7-2
Sonic Mania defeated Gorogoa 7-3
Uncharted defeated Nex Machina 13-3
Nothing out of the ordinary on opening day. Though I'd like to point out the bitter irony with Ultra Sun/Moon. 2016's Sun/Moon loses to Dark Souls III in the finals, while Ultra Sun/Moon loses to the samurai version of Dark Souls in 2017's opening round.
