What is this list?
Randomizers are hacks, mods and utilities that randomize video games in a way that significantly increase their replayability. Their randomization are applied before or when starting a new game in order to effectively generate many different games to experience based off the originals. They are also designed to prevent unwinnable states or introduce new potential softlocks as much as possible.
This list shows all randomizers known to me, listed by the games they randomize and grouped by game series, along with the randomizer's name in parentheses and documentation whenever necessary. I update the list frequently and try to keep it up-to-date to the best of my abilities.
In order to prevent the list from being polluted with entries that do not conform to the above, the following is not considered sufficient for inclusion:
- Original games and official ports.
- Randomizers that are not available publicly or that are still in a pre-alpha state.
- Graphics, audio or any other modifications that do not significantly affect gameplay.
- Randomization that can easily be applied without game modifications.
- Randomization that is not persistent within the same playthrough.
- Recurrent object swapping during gameplay.
- Object injection within original game areas.
- Chaotic effects.
The following rules are used to determine the game name showed in the list:
- For games with different versions, the list refers to the base game name only, unless an alternate version has significantly different gameplay content in which case it is considered a separate game.
- For games with official expansions or downloadable content, only the base game name is listed, even if said expansions or DLCs are required for the associated randomizer to work.
- If at least one official English name exists, the most current one is used, with American English priorized over European English.
- Official Japanese names with no official English equivalent are romanized in international Kunrei-shiki, with the exception of katakana which is directly translated.
- Whenever different games have identical names, the list refers to the one originally released, unless explicitely specified.
- Legal characters are omitted, and uppercase used for emphasis only are changed to title case.
If you ever notice a video game randomizer valid for inclusion that is not already listed, please contact me so I can add it! Special thanks to the numerous contributors so far that have made this list what it is today!
I want more!
You can look for the Randomizer tag on Twitch to easily find channels streaming live randomizer video content. In particular, the RandoMania channel almost exclusively streams such content, including speedrunning tournaments.
You can chat with other randomizer enthusiasts on the Randomizer Central Discord community.
For those interested in creating randomizers, ROMHacking.net is a good place to start learning how to do so.
For those that perfer an original game experience but still want to experience a randomized challenge, Retro Bravery and Hitman Roulette can generate interesting rulesets with randomized goals for many classic video games.
Honorable mention: The Nintendo 64 version of Resident Evil 2 contains an unlockable Randomizer mode. As far as I'm aware, it is the very first item randomizer in a video game.
Dishonorable mention: The Genesis version of Action 52 contains a Randomizer mode, but all it does is pick a game at random. As far as I'm aware, it is the earliest use of the term "Randomizer" in a video game.
