I did also put the game aside after my first try, I had no idea what to do, no idea how the interface was working .. and wtf ? a game where I have to look at my calories ? no way !
Then I came back a month later, watched some videos, played sandbox to get the basics, played the (well done) story, and now I interlope my way in the GreatBear
1101 hours of entertainment later, I confirm the Long Dark is definatly worth going through the first frustrations.
The mechanics are very simple, you can focus on your journey, there are no silly complex combinations to craft things.
Watch the survival guide, give it another try.
