“Not sold” is the storefront’s own answer on the last poll; nothing is inferred from a missing price. 40 storefronts polled 6 Sep 2026. 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.
Basis: 40 storefronts polled 6 Sep 2026; 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.

Ticks are the store page’s own language box, read 7 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. Data by SteamPeaks.com.
Every amount is a price Steam quotes on the USD sheet today, discounts included; nothing is converted. The DLC count is every app the store page lists under DLC, and a total that says “of N priced” adds only the DLC with a price on the sheet. Package prices are not read, so a bundle is listed as a way to own the set, not as a price. Data by SteamPeaks.com.
