* BrokenBase: Nearly every game released by them is divisive. While most agree that they're all ''extremely'' [[LevelGrinding grind-focused]], whether they manage to be good in spite of this fact is a hot topic of debate. Supporters cite interesting stories and character designs as major positives that make up for the middling gameplay, while detractors accuse them of having overwrought and undercooked stories that frequently border on being incomprehensible and further critique their tendency to recycle assets and gameplay mechanics over and over again.
* ContinuityLockout: Good luck understanding anything going on in any game in their ''Neverland'' series, which features a frankly staggering amount of lore covered across dozens of different titles. The games always take the stance that you know everything and make no effort to explain things that refer to events that happened in earlier titles, so you're pretty much guaranteed to be confused as to what is actually happening ''at least'' once.
* EnjoyTheStorySkipTheGame: A common take from genuine fans of the company, particularly those deep into the lore of the ''Neverland'' series. Their games tend to have middling and repetitive gameplay at best, but their interesting characters and complex storylines make up for it.
* FanNickname: For a given value of "fan". They're often referred to as Idea F*cktory on Japanese image boards due to their infamous track record of releasing games of debatable quality.
* MemeticMutation: Characters in Idea Factory games have ''very'' loud footsteps, which people like to poke fun at.
* TheyWastedAPerfectlyGoodCharacter: Their games tend to have many characters, almost all of whom receive expansive backstories in their character profiles. Unfortunately, most are lucky to get more than a few lines within the games themselves, and very few of them receive any kind of introduction or explanation as to who they even ''are'' outside of the aforementioned profiles, meaning a depressingly high number of them have completely wasted potential.
