Base Licence Identification
A valid-looking key string is not enough to make a safe purchase. The buyer must know redemption store, platform, account-region eligibility, and whether it unlocks a base game, a Deluxe upgrade, or only a bonus. The platform's own store listing remains the lowest-risk licence route.
Steam and Upgrade Distinction
It does not validate reseller keys. Limited Run's separate game and upgrade code descriptions show why a seller must say exactly what type of entitlement is being sold.
Safe Code Purchase Checks
Before paying, obtain the store, edition, regional restriction, unused-code policy, and seller refund terms. A preorder bonus or Deluxe upgrade never proves that the base licence is included. Transaction-specific validity keeps this answer noindex.
