This is not a review just praising the game as I give a 10/10 is enough to said it all.
Pros:
1. Stunning Environmental Background (eg. amusement park, inside missile tower)
2. Outstanding Music
3. Intense Dramatic Story & Setting
4. Emotionally Impactful Ending
5. Gameplay Switch (action rpg , shooter, minigame)
6. Player's Choice (can go deep into rpg element and slowly trying to upgrade everything, or just completing the main storyline as a fast-paced action game)
7. Style of Story Telling (achieiving each ending and begining the new, makes me feel like playing part 2 and 3 of the game)
8. Suitable for Both New Players and Old Nier & Drakengard Games (some characters and documents refer back to the series, which I consider to be additional, as I never played previous games and still fully enjoy this)
9. Not Easy, but Not Frustrating
10. Option to Choose Japanese Voice :)
Cons:
1. Confusing Map (can't find a way to get to some places when looking at the map)
2. Too Easy Final Fight (spoiler!!!-> fighting A2 or 9S is much easier than fighting Eve)
3. Demand Heavy Graphics (some players have to find a modification program and lower lighting effect, in order to get constant 60FPS - check out "FAR" mod)
4. Late Release in some Steam Regions
ps.previous games in the series should port to PC as well, and many people will buy it after playing Nier:Automata
