Design an intergalactic board game where players are space explorers competing to establish the most successful business empire on uncharted planets. Incorporate elements of resource management, extraterrestrial diplomacy, and cosmic strategy in your futuristic artwork.

Design an intergalactic board game showcasing a vividly-colored universe teeming with potential. Pictorial representations of multiple space explorers of various genders and descents are in the midst of space exploration. They are competitively vying to establish the most prosperous business empires on uncharted, alien planets. The game should feature elements that signify resource management, from simulated minerals to space credits. Imagery that represents extraterrestrial diplomacy, such as symbolic alien life forms engaged in peaceful negotiation, can be a part of the game. Finally, the board should be divided into unique cosmic sectors that indicate different strategic options for the players.
