Highlights games on GameSieve that are owned on GOG
A userscript that highlights games you own on GOG while browsing GameSieve. Makes it easy to identify which games in the GameSieve list are already part of your GOG library.

The script performs several operations to identify and highlight the games you own:
The script uses caching to improve performance:
You can modify these variables at the top of the script to customize its behavior:
// Configuration
const DEBUG = false; // Set to true to enable detailed console logging
const OWNED_GAMES_TTL = 60 * 60 * 1000; // 1 hour in milliseconds
const MAPPING_TTL = (14 * 24 * 60 * 60 * 1000) + (Math.random() * 100 * 60 * 60 * 1000); // 2 weeks + random 100 hours
const HIGHLIGHT_COLOR = '#bc9aca"; // GOG color
DEBUG: When set to true, enables detailed logging of the script's operations in the browser consoleOWNED_GAMES_TTL: How long to cache the list of owned games (in milliseconds)MAPPING_TTL: How long to cache the product ID to slug mappings (in milliseconds)HIGHLIGHT_COLOR: The background color to use for highlighting owned gamesThis script only accesses your owned games data from GOG.com to determine which games to highlight. It does not collect, store, or transmit any personal information. All data is stored locally in your browser and is not shared with any third parties.
