yea man definitely those games u listed are "must have" to play. They are so good, especially NieR:Auomata and NieR Replicant/NieR, but yea believe me ending E is worth playing remastered version, but yea if u dont have Ps4, then play normal NieR, u can allways watch Ending E somewhere, but I have a lot of emotions playing it, it was so good
