* CreatorKiller: Poor reviews and poor sales of the game were the final nail in the coffin for Traveler's Tales Oxford, and they would shut down as a result.
* DeletedScene: There are many cutscenes that ended up reaching the storyboard stage, with some even being voiced, but unfortunately [[WhatCouldHaveBeen had to be cut like a lot of other content in the game]]. [[https://www.youtube.com/playlist?list=PL9D33F6B9DDDBF83C Some can be viewed here]].
* TheOtherDarrin:
** The first game in which Creator/LexLang replaced Creator/ClancyBrown as the voice of Dr. Neo Cortex. He became the regular voice of Cortex from there.
** In an interesting note, this is the last game to feature any English cast members from the Naughty Dog games. Mel Winkler voiced Aku Aku for the last time in this title before being replaced by Greg Eagles in ''VideoGame/CrashOfTheTitans'', while Michael Ensign, who had reprised his role as Dr. Nefarious Tropy in ''Nitro Kart'', returned for Tropy's two scenes in this game. None of the original cast have returned since, including the ''N. Sane Trilogy''.
* TroubledProduction: An ''astounding'' example of this. There's loads of missing content, unused ideas, and whole models that ended up getting thrown out. As a result, the game is pitifully unfinished, even if it's pretty fun.
** The game was in development around the same time as the original ''LEGO Star Wars'', and most of its budget was being funneled to that instead, seeing as a license like Star Wars would be a much more profitable choice.
* WhatCouldHaveBeen:
** Collecting yellow gems unlocks "unseen extras" which apparently feature ideas and concepts that never made it into the final version. This is lampshaded by Cortex once: "We were going to visit two dimensions, but... we ran out of time."
** Several hours worth of content was removed from the game, including several returning characters, new levels, and a VillainSong for Dr. Cortex entitled "Take a Walk Inside My Brains". Two members of the development team released a great deal of information on these removed items, which can be viewed [[http://www.crashmania.net/?menu=ts&page=concepts here.]]
** At least two direct sequels were also planned, but never made it past early planning due to Traveler's Tales' Oxford unit shutting down.
** There were plans for a Gamecube port, but due to difficulties with porting the engine, the port was scrapped
