| Stakeholder | Recommendation | |-------------|----------------| | | Always launch games from the Steam client, not standalone executables. Keep Steam updated. Avoid “game cracking” tools that replace Steam API DLLs. | | Game Developers | Avoid OneShot initialization for the main game executable. Use asynchronous initialization ( k_EInitType_None ) and provide a retry mechanism. Fall back to normal init if OneShot fails. | | System Administrators | On managed/gaming café PCs, ensure the Steam service starts automatically at boot with -silent flag. Deploy a scheduled task to restart Steam weekly to clear stale API handles. |
