Confirm the identity before the inventory
Check the title, publisher, edition and language on the box and rulebook. Ask whether expansions have been mixed in or original components replaced. If the listing uses a stock photograph, request pictures of the actual contents. A component list from a different edition can make a complete game appear incomplete, or hide a genuine shortage.
Read the rules enough to know which pieces have unique functions. Missing one generic counter may have a different impact from missing a numbered scenario card. Do not assume a substitute is acceptable merely because it looks similar. Some components must remain indistinguishable in a bag or deck.
Count by functional groups
Start with boards, player sets, unique cards and special tokens. Then count large pools of interchangeable pieces. Compare both sides of double-sided components when relevant. Cards can stick together, so count carefully rather than estimating from deck thickness. Check that decks contain the expected ranges or types without exposing sealed spoilers unnecessarily.
Ask the seller to separate base-game and expansion materials if they are combined. An expansion can add enough extra pieces to make the box look complete while a crucial base component is absent. If separation is impractical, request a clear account of what has been verified and what remains uncertain.
Inspect wear that affects information
Look for bent corners, distinctive marks and uneven card backs. Cosmetic wear can become a gameplay issue when a hidden card is recognisable before it is drawn. Sleeves may conceal some back marks, but they do not repair missing text or guarantee that every card feels identical. Include any needed replacement or sleeving cost in your decision.
Check boards for damage that obscures spaces or prevents them lying reasonably flat. Inspect connectors, stands and moving parts if the game relies on them. Ask about odours, moisture exposure and sticky residue. A photograph may show surface wear but cannot fully communicate those conditions, so clarify them explicitly when buying remotely.
Treat campaign state as part of condition
Find out whether envelopes were opened, cards removed, stickers applied or sheets written on. Some campaign games provide a reset procedure; others involve changes that are difficult or impossible to reverse completely. Check the specific publisher instructions rather than accepting a general claim that it can be reset.
Ask whether all removed materials were retained and whether replacement packs are actually available for that edition. Do not price the purchase on the assumption that missing consumables can easily be bought later. If the game contains mystery solutions, previous marking or rearrangement may reveal information even when every physical piece remains present.
Verify digital and language requirements
If the game needs an app, account, code or online service, inspect the publisher's current requirements before buying. Determine whether an included code is reusable or has already been redeemed. A complete physical inventory does not by itself confirm that a required digital part can be used by a new owner.
Check component language, not just the rulebook. A downloadable translation of the rules may not cover text-heavy cards. Make sure the people who will play can use the actual copy. If fan-made replacement text is included, ask how it was produced and whether it matches the edition rather than assuming it is official.
Agree on the condition in concrete terms
Use specific descriptions such as all cards counted, one player marker replaced or campaign envelopes opened through a named stage. Broad terms like excellent or complete can mean different things to different sellers. Keep the agreed description with the purchase details so there is a shared reference if a problem appears.
When the contents cannot be checked, decide whether you are willing to accept that uncertainty at the offered price. It may be sensible to pass on a complicated incomplete game even when the discount is large. The useful comparison is the cost of a playable copy, including time and replacement work, rather than the lowest visible listing price.
