New Game

Im trying to make a survival game, im thinking of basics, thirst, food, craft, build etc,but i've run out of ideas, any tip?

Do you have any direct inspiration, i.e games or books that you wanted to base your game off of?

rust with better movment system would be pretty cool

7 Days to Die comes to mind? Or Fallout NV with Hardcore mode on

focus on more of an end game. sometimes the rewards are worth the pain and the punishment but a lot of survival games focus more on the normal elements and the slow build. like needing a certain amount of supplies to be able to make trip or having the right gear to handle different areas
