A now-defunct VideoGame studio based in [[UsefulNotes/{{Canada}} St. Catharines, Ontario]] that was founded by Denis Dyack in 1992. The company started out working on strategy games for home computers, but moved on to consoles after 1996. The company acquired fame in the early 2000's during their brief, close partnership with Creator/{{Nintendo}} before moving on.

In 2007, Silicon Knights [[FrivolousLawsuit sued]] Creator/EpicGames for selling them an unfinished and inferior version of the Unreal Engine 3. Epic Games [[GoneHorriblyWrong sued them back]], countering that Silicon Knights had rewritten some but not all of the Unreal Engine 3 code and [[WhatAnIdiot tried to claim]] the resulting mish-mash [[UsefulNotes/{{Plagiarism}} as their own work]], without crediting Epic or paying them royalties. In 2012, [[HoistByHisOwnPetard Epic won]], and the judge ordered Silicon Knights to recall and destroy all unsold copies of ''VideoGame/TooHuman'' and ''VideoGame/XMenDestiny'' at their own expense, delete the source code for both games plus three more games that were in development, and allow Epic Games access to the [=SK=] servers to ensure that all the offending code had been deleted. [[CreatorKiller Add to that the $9 million they owe in damages and legal fees plus the $4 million they already owed to the Canadian government, and it's pretty safe to say that Silicon Knights is no more]].

* CreatorKiller: If ''VideoGame/TooHuman'' and ''VideoGame/XMenDestiny'''s poor performance didn't kill them off, the spectacular backfire of their lawsuit against Creator/EpicGames certainly did.
* MagnumOpusDissonance: ''VideoGame/TooHuman'' was Denis Dyack's baby, but hardly any gamers shed a tear when the game got ScrewedByTheLawyers. On the other hand, much was lamented over the loss of most chances of getting a sequel to ''VideoGame/EternalDarkness''.
* ProtectionFromEditors: Silicon Knights, while being published by Nintendo and Konami, was under strong editorial control because those companies had quality brand names to protect. The success of ''VideoGame/EternalDarkness'' and ''[[Videogame/MetalGearSolid Metal Gear Solid: The Twin Snakes]]'' earned SK a lot of clout to shrug off the editorial control. Unfortunately for them, what followed were two [[VideoGame/TooHuman major]] [[VideoGame/XMenDestiny flops]].
* StillbornFranchise:
** ''VideoGame/TooHuman'' was supposed to be a trilogy, but the poor sales of the first game combined with the company's implosion has made further installments highly unlikely.
** ''VideoGame/EternalDarkness'' also had many fans clamoring for a sequel, which Silicon Knights was interested in providing, but they didn't get around to it in time. Two separate attempts were launched by SK to crowd source a SpiritualSuccessor to the game but both fell far short of their funding goals.
* {{UnPerson}}: Almost. When people started leaving the development team of ''X-Men Destiny'' due to being laid off, their names were taken out of the credits due to a policy previously created by Denis Dyack. The names were put back in, but under the "Special Thanks" section.
* WhatCouldHaveBeen: A game based on Creator/NeilGaiman's ''ComicBook/TheSandman'' was apparently in development at one point.
