I play on default medium and it seems fine to me. especially once you get some stuff built up. Food is such a deep part of the game mechanics I can’t imagine turning it off. Also that disables achievements and my gf loves numbers go up.
I sometimes come across as blunt so prefacing this to make sure you know I don’t mean to be rude Tman ;) At any rate, water is easy to find. Just look up at drops on blades of grass. Either hit the grass then grab the water or shoot the drop with ranged weapon and grab both water and arrow/weapon. Also a canteen helps alleviate dependence on it later.
You can easily place markers pretty much anywhere, you can also build trail beacons/markers which show up on your hud. I have one for each base/outpost I make as well as important resource gathering spots I want to find easily. I have a red one for my main base blue for my outpost and so on. I just aim at the red home icon and go. No map needed.
Dry grass is really yellow or brown, grass is very green. If you are color blind though it could be difficult I guess. they are drastically different colors in most areas though. There are a couple exceptions.
Put a marker near your lean-to as well, or look for the ghost symbol on the map. Torches work well as well if out a bit late. Day/night is fast, maximize work in day, then just sleep and repeat. Later in game there will be reasons to go out at night.
a lot of these are either told to you as you complete tutorial tasks or are available in the survival guide in the game’s menu.
again, really not trying to sound harsh I just really enjoy the game and don’t like it getting criticized for things that aren’t really issues. there are plenty of things to complain about though, I just don’t know that any of these would be since the game provides the tools and info for them.
another part of finding your way around is simply learning the map and getting familiar with different areas though. I play a lot with my girlfriend and thought it was kind of neat when she saw a video on youtube showing a building technique and in just a couple seconds noticed and shouted that ‘this is the area of our second outpost!’ and was proud she recognized it.
Take your time with learning and pushing the story, there are a few things that are important to get quickly but really on the first playthrough I would just take your time and make sure you are learning what the game is trying to tell you. There are some decent ‘wish I had known earlier’ videos on youtube as well and so far I’ve been pretty lucky with them being mostly spoiler free.
