The Biscuit Billionaire

Wyatt Hale, a programmer tired of his boss making empty promises, uses the 'Promise Fulfillment System' to fight back and escape the life of a corporate drone. He establishes a company in The Wastes that doesn't make empty promises, while also using gold from The Wastes to gain immense wealth in the real world. He ensures his promise-making boss gets his comeuppance, ultimately becoming both the master of The Wastes and the richest man in the real world.
