    Debug.LogError("Steam API initialization failed");
    return;
}

For Unreal Engine: Use the built-in Online Subsystem Steam plugin for seamless integration.

Phase 3: Store Page Creation

    if (SteamManager.Initialized) {
        SteamUserStats.SetAchievement(achievementID);
        SteamUserStats.StoreStats();
    }
}

Steam Cloud Save Integration: Enable automatic save synchronization across player devices. This feature is especially important for Steam Deck compatibility.

Workshop Integration: If your game supports user-generated content, Steam Workshop integration can dramatically extend its lifespan and community engagement.

Multi-Platform Considerations

Steam Deck Compatibility: In 2025, Steam Deck compatibility is increasingly important:

• Test your game on Steam Deck or similar hardware
• Ensure UI elements are readable at 1280×800 resolution
