Gold Fever (NGL) is a player-owned, survival MMORPG set in a dark and haunting rainforest. The game incorporates a blockchain economy driven by Commercial NFTs, enabling players to mine and compete for NGL. The game's unique dynamics allow players to develop infrastructure, acquire planes, and receive compensation by renting them to others. The introduction of commercial NFTs, in-game businesses that provide items and services, has facilitated full decentralization and ownership of the entire game. Gold Fever aims to provide a reliable metaverse, transforming what was once an amusement into a potential source of compensation.

Gold Fever operates on a complex strategy, leveraging blockchain design to incentivize cooperation between players. The game encourages players to act according to economic incentives, allowing them to earn NGL while playing. The game's plot is set in an unforgiving wilderness, where a gold rush pits two factions against each other: Tribes and Adventurers. Players can align with either faction and take different roles, with the battle over mining claims taking place between these different roles. The game also introduces the role of Thieves, who can steal the gold of mining claim owners, creating a highly complex and strategic gameplay.

Gold Fever offers a unique use case concept for NFTs - in-game businesses that provide items and services for game players. These commercial NFTs can potentially generate passive compensation or can be rented or put in custody. Players can accumulate resources in four ways: by grinding for gold and exchanging it at the bank, by destroying, killing and recovering gold as a Tribal, by owning a commercial NFT business that produces items and services, and by exploiting land for gold or using it to build on. The game also utilizes four different types of tokens, including NGL, which is used to facilitate gameplay, access, and unlock rights and privileges.

Gold Fever was launched by Defi Mechanics Lab, a team that strives to combine gaming and crypto to create something unique for the players. The development is headed by Emilian Ciocanea, a serial entrepreneur with over two decades of experience. The game has been in development since Q4 2021, with the first beta released with Beta Island. Throughout 2022, the developers matured the game core-loop, added more infrastructure, enabled core functionalities of the in-game economy, and expanded the story. The team also developed commercial NFTs within a game-economy that reflects real-life economic systems, facilitating decentralization and player ownership within the game.
