YMMV: NiGHTS Into Dreams
Accidental Innuendo: Here's the first thing Reala says to a lost and confused little boy at an abandoned theme park in Journey Into Dreams:
Reala: Oh how I've waited for this moment! The opportunity to get you all alone, dear visitor! Now, how exactly should I go about getting what I want? Hmm?
Heck, it starts from the beginning of the game!
Owl: Go over and touch NiGHTS. You'll see what I mean. That is, of course if you're into that sort of thing.
Angst? What Angst?: NiGHTS certainly takes his/her entire species basically being out to get him/her in stride, although s/he does display signs of being bothered by Helen's reaction to learning that NiGHTS is a Nightmaren.
Big Name Fan: Shigeru Miyamoto, the creator of Mario and Zelda, has openly lauded this game as a masterpiece, saying it's the one game he wishes he could have made.
Crowning Music of Awesome: Pretty much the entire soundtrack, for both games, but especially the songs Dreams Dreams, NiGHTS and Reala, and The Mantle.
Don't forget about Wandering Wildness (the theme for Lost Park) and D'Force Master (the final boss theme) in Journey of Dreams.
Ensemble Darkhorse: Jackle, to the point where people who never played the original game love the card-throwing crazy.
Fandom Berserk Button: Some people can be very insistent about ensuring that the title character's name is capitalized as NiGHTS, not Nights or NIGHTS.
Fan Dumb: Despite the Word of God saying that NiGHTS is genderless, many fans still adamantly insist that s/he's one gender or the other. Directly referring to NiGHTS with male pronouns in Journey of Dreams didn't really help matters, though it was probably done for convenience's sake.
They're split fifty/fifty with regards to his/her gender, but each side is adamant that they're correct. More sensible fans don't mind what you call NiGHTS, and only get annoyed if you try to insist that s/he's got a canon gender.
Nightmare Fuel: Ignoring the fact that you play as a living nightmare (however friendly) and fight other nightmares, the opening cutscenes in Journey of Dreams are pretty creepy.
The scene where Wizeman states his intention to erase NiGHTS' personality, thus turning his/her into an obedient servant. It's also possibly an example of And I Must Scream; at the least, it's a Fate Worse than Death.
Claris's opening with the judges turning into demons and chasing her through a psychedelic landscape.
Sequelitis: Many fans believe that the second game, Journey of Dreams, is inferior to the original.
Tear Jerker: In the "Yellow Ideya" ending when NiGHTS reveals that s/he knows that s/he'll die if Wizeman is destroyed, saying that s/he's "known it all along", and then fights him anyway. After Wizeman is defeated, s/he takes one final bow and dissolves into light. Also counts as the character's Crowning Moment Of Awesome.
Helen and Will's reactions don't really help.
True. The shots of them waking up and crying, with their tears falling onto whatever they're holding, only adds to the sorrow of the moment.
That One Boss: Bomamba, a witch whom you have to beat by tilting malevolent cat heads into holes. Odd physics mean it's mostly luck if any fall through. It's timed, too, just to add insult to injury. Jackle may also qualify.
And if Jackle doesn't qualify, Wizeman's battle in the first game definitely does. The fireballs and giant snowballs are easy enough to dodge, but the rows of stones will trap and kill you if you misjudge their movement. The worst is the tornado formed like a time glass — there's a small hole right in the middle of it, but you can only fit if you Drilldash, and it's very easy to miss.
Chamelon is a Guide Dang It sort of boss. Once you know what to do, executing it isn't too hard... so long as you don't dawdle at all and have reasonable luck.
