Played through both NieR games. I think Automata is a more solidly-structured and paced product but I kind of struggled with the gameplay compared to Replicant, the enemies felt like bullet-sponges a lot of the time, and in both games the heavy swords are way too slow for any potential increase in damage.
Still, a pretty interesting experience throughout both. Not many games manage to both be incredibly depressing and also first-class waifu generators at the same time. They usually just switch between one or the other.
