Astroneer is a great game as it is but it is in it's alpha stage meaning there is lots for to add. One of my ideas is that Astroneer should contain more survival like essentials. Here are two of my ideas:
1. Food - I believe food should be an item in this game to make it more challenging but before creating a server there would be a difficulty option which change the amount of food you would need daily to survive. Food could be obtained from destroyed ships, killing plants, and from organics. On the hardest difficulty you would need five units of food each day. On medium you would need three each day. On easy you would only need to eat one.
2. Drinking Water- Just like food, water would add a more survival like aspect to the game. Changeing difficulty would also change the amount needed. Water could be abtained by filling a canister with soil then extracting a material, using the material extractor, leaving behind a canister with some fresh ground water. On a hard difficulty you would need to drink five units a day. On medium, three, and on easy you would need one.
