Share some games you will use to draw inspirations from.
Some games that comes to mind is: Time Fcuk, The Swapper, Lemmings, One Chance, Dead in Bermuda.
Some of my ideas so far are
• Survival village. There's not enough resources for everyone so some has to be exiled, but everyone has a valuable skill to contribute with that will be lost.
• Vampire survival. Can you survive long enough to discover a cure without feasting on your loved ones?
• Trolley dilemma. Will you intervene? You have the chance to save 5 people by sacrificing 1. Now you'll have to live with the consequences.
• Mutagen. Platformer where the obstacles arn't deadly, but increase your exposure to a deadly virus. Make to many mistakes and you have a higher chance to expose the world to it. Will you sacrifice yourself then and start all over, or do you want to get to the end no matter the cost?
• Family survival. You gather resources for your family, but along the way you meet groups of starving people. Will you help them with time or resources depriving your family? Some choices might bring benefits in the future.
• Short term vs Long term benefits. Game where you choose between quick logarithmic growth, vs slow exponential growth (income, skills).
