Basis: no storefront polled yet; closures are read daily from the app’s own Steam news feed with the sentence the date came from; a store page counts as removed only after two polls 24 hours apart both fail. Playable after is a reading of the store’s categories and detected online services, not a promise about the game. Data by SteamPeaks.com.
“Not sold” is the storefront’s own answer on the last poll; nothing is inferred from a missing price. A date is the moment the answer flipped between two polls; “since the first poll” means it was already withheld when polling began, and no earlier claim is made. Data by SteamPeaks.com.
The ledger starts 3 Sep 2026; changes before that day are not claimed. Each row keeps the old and new wording as the store printed it, or the bare day PICS reported, and the slip when both sides are dates. Data by SteamPeaks.com.

Ticks are the store page’s own language box, read 19 Sep 2026, with the PICS list standing in where the box has not been read. Demand is Steam’s per-language review totals: reviews written in a language, never players. Changes come from the store-field ledger, which began on 3 Sep 2026; none on record for this game yet.
