I started this project for the BGMC 22 challenge, but since I never have enough free time to finish the game in time its out of the contest.
The idea:
You are in space, in a small spaceship. There are 3 other people in there with you. Each one of them has an assignment ( Navigation, Engines, Weapons ), you are the Explorer/Captain.
The game would be divided into missions, and missions would be released with updates to the game.
They do sound similar because of planets and space. My graphics style is going in a completely different direction so the end result could be two very different games. Good luck
