i've written my own little review for fun a while ago for this game, so i thought why not post it here:
recently i've had the pleasure to be immersed in this great game, and it got me very much hooked, except a few moments here and there that ill delve more into with more details up ahead.
the story in this game very much revels in having a great narrative, and less so much in having a lore that goes to great length to expand the game's world, although you can go visit the previous nier games to get details on the past civilizations and such. and while the narrative has a great depth to it with questioning not only existentialism and meaningness that reflects upon us living breathing beings, but it's application to androids and machines. There are moments in this game that really delve deeply into the consciousness debate of AI, machines vs humans. i.e the time when you meet a pair of machines that express their biologically bonding of one another - mother and son, and then you see 9s comments that it probably only means that they are made from the same manufacture, and then as time goes on, 9s and 2b are more inclined to believe of the prevalence of consciousness in machines. The combat doesn't have the amount of combos orders that you can find in other games of the same type like ninja gaiden or bayonetta, and it is more simplistic, which is a little bit of a drawback as someone that appreciates very much combo series of attacks in hack n slash games. But there are other areas at least the combat compensates for it, as you can see with 9s segments and combat, where he can hack and remote control machines, which can result in great oily splashes (instead of blood :)) of battles. Actually, in a matter of fact no, there is not any oil dripping involved by the machines' death, but you still get the point :)
the way the difficulty scales in this game, doesn't make the game's AI gradually more sophisticated, or is in the vein of making the enemies dodge more, or change their attack pattern of light attack and special other ones to make it harder. But rather the difficulty's scallibility wears it more like a hitting sponge regarding It's health pool, by letting the enemies deal more damage, meaning that only their strength paramaters are changed, not behavioral. The music in this game is very beautiful, awe inspiring and unique. It has some really emotional tones, and other sounding more epic.
To sum things up, I very much recommend this to anyone that is looking for a deep narrative focused game, with competent combat to back it up, good characters interactions between 2b 'the stoic' type, and 9s the playful guy and other different characters. a score of 8.3 from me.
