History YMMV / NicktoonsUnite

* UnintentionalPeriodPiece: The inclusion of shows that were airing at the time of the game's release but have since ended such as ''WesternAnimation/DannyPhantom'' and ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' solidly dates the games to the mid-2000s - while characters from said shows have appeared in later {{Creator/Nickelodeon}} games, it's unlikely they'd be the central focus if the series was made today. Especially notable with ''Toybots'' and ''Globs of Doom'''s focus on ''WesternAnimation/TakAndThePowerOfJuju'', a series that only lasted one season, was critically panned and is highly obscure by modern standards. It's also definitely the only time when ''WesternAnimation/TheFairlyOddParents'' (heavily pushed in that era, a forgotten and oft-mocked afterthought any time thereafter due to a legendary case of SeasonalRot) would have ever been trumpeted as a major player in the game. Tellingly, ''VideoGame/NickelodeonKartRacers'' and ''VideoGame/NickelodeonAllStarBrawl'' (released in 2018 and 2021 respectively) don't feature ''The Fairly [=OddParents=]'' at all.

* GoddamnedBoss: Toybots DS's Tak-bot isn't terribly difficult on its own, instead the challenge comes from trying to make it vulnerable in the first place. Only after hitting three roulettes and three targets that put you in danger of hitting yourself due to how boss arenas are laid out will the Tak-bot drop its invincibility… for a while. Before long, it'll put its defenses back up and force you to do the whole thing again, making for a very slow, drawn-out battle.

** The DS version has a remarkably good soundtrack overall, but special mention has to go to the tracks for [[https://www.youtube.com/watch?v=ifm1q1t234k Green Hill 1]][[note]]Not to be confused with the ''VideoGame/SonicTheHedgehog1'' stage and theme of the [[NamesTheSame same name]][[/note]], [[https://www.youtube.com/watch?v=zQmN-92LgiA&list=PLiNIqLOdbvW0DELOhU75fuclx0nCzKD0g&index=30 Vortex Volcano 2]], and [[https://www.youtube.com/watch?v=Fq2gHd4Fc6E the boss theme]], which all ''slap''.

** [[AdvertisedExtra Despite being placed right in the middle of the cover]] and being both the main character of one of Nick's most beloved franchises and present throughout all of the previous game, Timmy Turner is only playable in a single level of ''Volcano Island''. He would later return in ''Toybots'', only to be absent altogether from ''Globs of Doom''.

** The Giant Fleabot in the console version of ''Nicktoons Unite!'' is the hardest boss of the game, given that various Mooks pop up all over the place, and the openings you have to defeat the fleabot is very slim.

* TheProblemWithLicensedGames: While the first three games in the series were largely surprisingly decent affairs and serious {{Cult Classic}}s, there's not much love for the final installment ''Globs of Doom'', which seemed to lack the actual effort that was put into the previous games in terms of the gameplay (generic, monotonous, and [[ItsEasySoItSucks too easy]]), graphics (the characters look OffModel at best and [[UncannyValley outright hideous]] at worst), and story (the Nicktoon characters besides [=SpongeBob=] are pretty much an afterthought [hence the ''[=SpongeBob=] [=SquarePants=] featuring...'' part in the beginning of the title] and the mainstay ''Fairly [=OddParents=]!'' characters like Timmy Turner are inexplicably missing). On top of that, the game was [[GameBreakingBug far more bug-ridden than any of the previous games]], including one severe save-corrupting bug. The developers dropped the ball so badly that [[FranchiseKiller it outright killed]] the ''Nicktoons Unite'' series and no Nickelodeon crossover games on dedicated video game consoles have been platforming adventures since.[[note]] Additionally, it would take another three years for ''any'' Nicktoons crossover game to be made with ''VideoGame/NicktoonsMLB'' in 2011, and another seven years after that for the next one, ''VideoGame/NickelodeonKartRacers'', to be made in 2018.[[/note]]

* UncannyValley:
** [[https://www.models-resource.com/resources/big_icons/7/6338.png Danny]] and [[https://www.models-resource.com/resources/big_icons/7/6120.png Timmy]] in the first three games, with Timmy in particular looking even worse than his ''WesternAnimation/TheJimmyTimmyPowerHour'' model. Averted in ''Globs of Doom'', where they finally managed to get [[http://www.behindthevoiceactors.com/_img/chars/danny-fenton-nicktoons-globs-of-doom-52.2.jpg Danny in 3D]] right.
** Jimmy in ''Globs of Doom''. You'd think that out of all of the Nicktoons converted to 3D, Jimmy, already being a 3D Nicktoon, would look the least uncanny, but his [[http://www.behindthevoiceactors.com/_img/chars/jimmy-neutron-nicktoons-globs-of-doom-9.46.jpg appearance]] [[https://www.youtube.com/watch?v=sP7U0lPKr7Q here]] makes him look like a walking corpse with no emotion whatsoever, or a CGI version of his Fairly [=OddParents=] design. Beautiful Gorgeous, [[WesternAnimation/TakAndThePowerOfJuju2007 Tak and Traloc]] all looked fine, so why couldn't they get Jimmy right? This is especially egregious considering [[https://www.models-resource.com/wii/nicktoonsattackofthetoybots/model/6113 his model in the first three games]] was decent-looking.

* DisappointingLastLevel: Calamitous' Lair in ''Toybots'' is just another mech suit stage with very little to differentiate it from Amity Park beyond a different backdrop - it doesn't even have a FinalBoss encounter, as the game abruptly ends after completing the final section.
