This is the BEST Neptunia game hands down, being the only one of them with "Overwhelmingly Positive" reviews is a statement to that.

Gameplay wise its your typical Neptunia turn based RPG, you position your character around and try to strike as many enemies as possible, you beat monsters and get XP and material, what makes it fun is the "remake" crafting system present since the first Re;Birth, You collect materials and plans that can change elements of the game, from making better items to upgrading characters to have more skills or HP to changing the enemies to be weaker or strong and being able to outright skip combat with the "destroy symbols" and "destroy symbols gain" plans (Of course you'll have to passively grind Stella's Dungeon for that last one).

However I'd say the gameplay comes second and what shines in this game are the characters and story, this is Videogame: The Videogame, as usual each character represents a console platform however in this one Neptune is sent to an alternate dimension whose story alludes to actual videogame history (E.g. Xbox reception in Japan, Crash of 1983, Sony and Nintendo fall-off which led to the Playstation etc), it's really neat and cute seeing those events be played out by the girls.

The new characters are great, don't let fraud youtubers or reddit prude f--s gaslight you about Plutia / Iris Heart, she is singlehandedly the best character this franchise ever had, the juxtaposition between her normal and HDD personalities lead to funny scenes, she is also the "Neptune" equivalent on Ultradimension, gluing all CPUs as friends. She does torture people and is a sadist, this is done to reflect Sega's spicy marketing approach in the good old days. She however does NOT sexually assault anyone, that's projection from legitimate predators.

The game has 3 endings, unlike the previous titles you do not need to balance the shares amoutn between nations, the requirements are far more easier and simple, if you just watch all events you're more than likely to get Good or True Endings, to get Normal Ending you need to go out of your way and NOT see 5 specific events at chapter 5 and 6 (Cue on more people having the Good / True ending achievments than the Normal Ending one). To then get the True ending you need at chapter 9 to watch 3 eggplant events and watch 5 events localized in some dungeons you might not have unlocked through the normal play. There is a really useful guide that goes through where and how.

About the localization, this is far better than the previous 2 games and does not require a fan patch in my opinion, however it's not 100% accurate specially with Neptune, being able to understand what they are saying I can verify that in some (not many) of her lines it will be translated correctly but there will be a whole ass sentences afterwards which she didn't say and said sentence makes her sound way more mean and ♥♥♥♥♥♥♥♥♥♥.

There's only 2 examples of bad localization I could spot (Need to revisit the start of the game as I started before I learned japanese), one was when Neptune was referencing "neppit" where in the audio she was referencing something called "fakkin", which I imagine alludes to some japanese forum of sorts, so understandable but eh. The second one was a line where she's just affirming something a character said before but in the text she is for some reason mocking breast sizes (?).

These annoyances aside, this game falls in to the better side of localized content, aside from Neptune everyone is true to their personality, even Plutia's slowness is translated in to looooooong woooorrds. I give the localization an 9/10.

Sadly I think the series peaked at this game, I'm not interested in Megadimension as it doesn't have Plutia, Peashy or any of the cool makers, most of the spinoffs are bad and after being burned out by Cyberdimension I'll only care about future Neptunia titles if Plutia is present (If they ever release more of them).
