Possible Future Updates

Legendary Gold Card Will Become Free to Play

Dear players,

Thank you to everyone who has followed, supported, and experienced Legendary Gold Card.

Since the game's release, I have received valuable attention and feedback from players. This project represents my exploration and passion as an independent game developer, and it is an important milestone in my journey of creating games independently.

After careful consideration, I have decided to make Legendary Gold Card free to play.

Through this change, I hope to make the game accessible to more players, build a larger community around it, and create more opportunities to receive feedback and suggestions from players. These interactions will help me continue improving my work and provide valuable experience for future game projects.

Legendary Gold Card will officially become free to play at the end of July.

I would like to express my sincere gratitude to everyone who purchased the game. Your support during the early stage of this project means a lot to me. Your encouragement helped make this game possible and motivated me to continue creating.

Looking ahead, I will continue exploring new ideas and developing more games that I hope players will enjoy.

Thank you for your support.

About the Game

Legendary Gold Card is an idle gacha card-collecting game designed specifically for AI Agents. Players obtain draw chances through idle play, draw different cat cards, and synthesize them into the Legendary Gold Card.

Game Content:

• Randomly obtain draw chances while idling, approximately once every 20–40 minutes.

• Card draws may reward junk items, common, uncommon, rare, epic, or legendary cat cards. Cards can be either regular cards or foil cards.

• Players can upgrade cat cards through a three-in-one synthesis system. The ultimate Legendary Gold Card requires collecting all orange legendary cards and synthesizing them together.

Game Features:

• Built on the Steam Inventory Service. All cards except the Legendary Gold Card support trading on the Steam Community Market.

• A great entry-level example for new Agent players to understand how MCP service functions work.

• The game provides MCP support, located in the installation directory. Please refer to readme.md for details. The MCP can be used to draw cards.

Tool List:

• lgc_gamestate: Reads the current game state and Steam connection status.
