Save/Continue writes: The Hyperdimension Neptunia series has always been a tongue-in-cheek poke at the modern console wars between Nintendo, Sony, and Microsoft, accompanied by the personification of the long-dreamed Sega Neptune as Neptunia herself. With Hyperdimension Neptunia: Producing Perfection, a comical non-canon entry exclusively for the PlayStation Vita, we see our lovable CPU Goddesses of Lastation, Lowee, Leanbox, and Planeptune attempt to put a stop to MOB48 (a play on popular idol group AKB48) from taking all the shares of Gamindustri by becoming idols themselves and winning back the hearts and dollars of their people.
VGChartz's Adam Cartwright: "Console wars have been around pretty much since the dawn of videogames, but the Hyperdimension Neptunia series makes light of these arguments by personifying consoles and their manufacturers as cute goddesses and has them battle it out for supremacy. It proved to be a sleeper hit for publisher Compile Heart, who after an initially shaky start with the first entry transformed the series into its most compelling franchise."
Destructoid:
"The Hyperdimension Neptunia series is a polarizing one. Some find Compile Heart’s thinly-veiled parodies of the game industry engaging and painfully adorable, and flock to it for an abundance of fanservice. Others run far, far away at the mere mention of the developer’s swath of content, especially given its less than lukewarm reception among critics and gaming publications."
Parallax Play: "In the latest adventure with the Gamindustry girls, they take a step out of their action RPG comfort zone and take a stab at becoming idols in this idol-management sim / parody game to face a new threat to their nations. If you’ve played any of the Hyperdimension Neptunia games before, you’ll know that you can expect to see copious amounts of references and parodies of games and companies in the real world."
Looks way too over the top for me.
