I have spotted an error with your FAQ:
2. How to Sleep Warm in Winter - You have it backwards, with fewer furs you "Lay on the furs", with more you "Wrap yourself in furs". Also spruce twigs can now insulate you from the worst of the groundfrost.
If I may also suggest some additions:
The game is traditionally permadeath, but there is a way to save scum ahem... I mean archive a save in case of a bug. Find the game directory, for Steam users usually C:\Program Files (x86)\Steam\steamapps\common\UnRealWorld and you'll see a folder there with your character's name. You can copy this to anywhere else before facing a bear possible situation where a bug may arise, then if you die shut down the game and copy the character folder back into the game directory.
It is a really, really good idea to set up your base on a rapids tile or where the sea doesn't freeze over. This way you aren't always having to break the ice for water in winter. Unless you're freezing or starving, always take the time to find a good spot before beginning building. I like to find somewhere with water just outside the front door, but also space for a tanning table (you can build "floors and ceiling" outside your cabin if there are two adjacent walls or doors, this means you can tan skins without getting frostbites in winter - well, mostly!)and a cellar, preferably designed so the walls of the cabin block access to any of this unless you wade through water to get there. Most predators won't wade through water, especially in winter.
Another way to keep valuables safe from home intruders is to push (shift-P) the valuables onto the walls of your cabin. Thieves can pick up your stuff, but only from the ground. You can also use the push command to display antlers, crossed swords etc. on your walls once you are sufficiently set up to bother with cosmetics!
A persistence hunter needs to be fast and use javelins, while someone with speed less than 6 km/h when dressed for hunting should probably use a bow or stick to trapping. Tracking skill is vital for persistence hunting - that is, chasing the prey down - and even a master tracker will still struggle to keep the trail. Snow makes tracks much more visible, and you will need skis. Some animals are designed for snow but many are not, and on skis you can run them down very quickly. Winter also means you can dry the meat, which is the best way to preserve it.
The northern coast has a really harsh winter, there are days when even if you are wearing everything you own you you will not be able to go half an hour without being next to a fire without getting frostbite. Stay in the south for milder climes. I had played for years before I became aware there was a difference!
Something else I took quite a while to realise existed was the Shift-A screen, detailing warmth and armour ratings. Also that making a general sacrifice after each kill is probably a good idea, even though nobody knows why. That's religion for you!
Great FAQ, as a long time player I already knew most of it, but the ability to strafe move was a new one on me. Every day a school day, cheers!
