Post
The expanding set of possible toys that a game slowly lets into future runs.
Unlock pools add new items, characters, cards, weapons, or events to the run generator over time. They create discovery but can also dilute consistency if the pool expands without curation.
Example
The Binding of Isaac, Enter the Gungeon, Vampire Survivors, and Hades all use unlock pools to keep familiar run structures producing new surprises.
Why it matters
Unlock pools matter because they are how many roguelites pace novelty across dozens or hundreds of attempts.
