I'm also playing Nier, and think it's pretty great. And that's from coming off of Horizon Zero Dawn, which is hard to follow (despite the pozz in the game).
HZD was amazing, the best game I played since Witcher 3. I think I'm gonna have to go with Witcher 3 as my favorite game of all time.
Childhood favorites include Final Fantasy 7-9, Xenogears, Chrono Cross, and Chrono Trigger.
Next games I have lined up are Witcher 3: Blood and Wine and Persona 5.
