Compatibility belongs to the game
A Steam account can contain games with different Steam Deck compatibility states. Check the titles you plan to play individually. A large library, a high profile level or an account’s general availability does not establish that every included game suits Deck.
Start with a short must-play list. A library with five games that fit your device can be more useful to you than a much larger library whose headline titles require compromises you do not want. The aim is to compare playable plans, not just library totals.

Read the category and its detail
Valve uses Verified, Playable, Unsupported and Unknown categories. Playable can involve manual adjustments; Unknown means Valve has not completed a compatibility assessment. Read the explanation attached to the exact game rather than treating all non-Verified labels as the same result.
Valve’s program considers input, display, seamless operation and system support. A category is a useful starting point, but your preferences still matter. For example, needing touchscreen interaction or adjusting controls may be acceptable to one player and inconvenient to another.
| Category | How to use it |
|---|---|
| Verified | A strong starting point for Deck use; inspect the game you want |
| Playable | Read the required adjustments and decide whether they suit you |
| Unsupported | Do not count it as an established Deck option |
| Unknown | Compatibility has not been established by that label |

Check the actual title and edition
Write each important game on a row and open its current Steam page or Library compatibility details. Record the category, any relevant notes and the date you checked. Compatibility can change with game or platform updates, so a screenshot from an older guide is not the same as a current check.
Keep the edition and DLC requirements next to that row. If the account only discloses a base game, do not assume an expansion is included because the game’s store page advertises it. Device suitability and account contents are separate parts of the decision.

Plan how you will use more than one device
If you intend to alternate between a desktop and Deck, inspect save support as well. Valve allows developers to choose how Steam Cloud is used. A Cloud feature label does not establish that every setting or every cross-operating-system save arrangement behaves identically.
For a long game, decide whether continuing the same campaign on both devices is essential. If it is, verify that game’s current save behavior before making it the reason for choosing a library. If you plan to start a separate campaign, that requirement may matter less to you.

Choose a library you can explain
An illustrative shortlist might contain three must-play games and two optional ones. Record which are disclosed on the account, their current Deck category and any adjustment you are comfortable making. This produces a practical comparison even when two accounts have very different total game counts.
Use the Steam catalog to find the named games, then carry out the per-title checks. Do not describe an entire account as Deck Verified: the program evaluates games. A clear wishlist with current compatibility evidence is more useful than a broad promise attached to a library.
