* AwesomeMusic:
** The opening theme "Ryuusei no Bifrost".
** [[http://www.youtube.com/watch?v=lYcIkkjL7E0 Leanbox's theme]], [[ExactlyWhatItSaysOnTheTin theme of...well, Leanbox.]]
** The song that plays during one of the trailers and during the credits, [[http://www.youtube.com/watch?v=-fyHtuPxOus Koi Wo Game Ni Shinaide!]], is quite catchy.
* CriticalDissonance: This game caters heavily towards otaku who love other Nippon Ichi games. Almost everyone outside of that group (including reviewers) hated it. There's a whopping 40 point difference between its [[http://www.metacritic.com/game/playstation-3/hyperdimension-neptunia professional and user reviews on Metacritic]]. No reviewer gave it a positive review. No user gave it a negative review.
* EarWorm: The infamous ''[[http://www.youtube.com/watch?v=S5zaO3U69_c Gamindustri's Comic Relief]]'', aka [[FanNickname DANANANANA NANANANANA]]. It's catchy as all hell, and plays whenever something silly happens (which is almost all the time). Most players can't get it to leave their heads.
* EvilIsSexy: Have you ever seen Arfoire's outfit?
* FirstInstallmentWins: Averted. The first installment is the one most people usually hate, due to the various problems it had.
* FunnyAneurysmMoment: This game was released in Japan back in August and it was advertising that the premise of the game was that Neptune and the gang were fighting against piracy. A few months later, someone successfully hacked the PlayStation3, but Sony fought off against it and sued the company for making the one thing that can hack the machine.
** With the April 2011 hacking of the PlayStationNetwork, you can be sure this game inspired the hackers.
* HollywoodPudgy: Neptune is stated several times to be "chubby" but looks no bigger than the rest of the girls.
* LesYay: With an all-female main cast, it was inevitable. One of the best examples is when Neptune snuggles Compa from behind with the intent to use her like a body pillow. IF provides the requisite lampshading.
--> IF: What the hell is this perverted crap?
** Iffy is something of a Les Yay magnet. Vert's actions towards her could easily be construed as this, she fangirls over 5pb, and Red takes her as the first wifey of her lesbian harem.
** Histoire takes this UpToEleven with her {{Emoticon}} usage.
* SoOkayItsAverage: While the game features a ton of video game references, fanservice, and has a pretty cool opening theme, the gameplay isn't so lucky. Compared to other recent [[EasternRPG JRPGs]], the dungeon design is extremely linear and uninspired. The combat system isn't too original, like that of the first four ''Xeno'' games, and the rest of the music is pretty okay. There's not too much unique gameplay-wise, and if one read the manga they could get virtually the same effect.
* ScrappyMechanic: What do you mean I can't heal outside of battles!? What do you mean I have to set some percentages just so my healing items can heal me DURING a battle!? Why are the potions too damn expensive!?
** What do you mean I don't get Black Heart, White Heart and Thunder Tits until right before the last dungeon!? What do you mean I [[LostForever can't get them at ALL]] if I let Neptune die too many times or I leave optional dungeons too many times?! What do you mean Gust and Nisa are DLC!?
* ThatOneBoss: The Killachine and CPU Breaker spell trouble even for HDD Neptune, and the fact that you have to fight one after the other makes it worse.
* TheyWastedAPerfectlyGoodPlot: The game hints a few times that Black Heart is lonely and has no friends. They never really do anything with this, which is a shame as it could've made for some nice character development.
** This is, however, a focus of her character in later installments.
