NieR Replicant is an awesome game, which I really like and enjoyed. Even though I think it was a bit repetitive at the end, especially with getting all the Endings, I still had a great time overall with it. Especially the music, the whole soundtrack of the game is fantastic, and totally fits in with the cutscenes and moments in which it plays.
I also very much liked the characters, with Kainé probably being my favorite out of the whole cast.
The game was definitely worth playing, and I'm glad that I finally did.
