So I've picked this one up, which has been around since 2014. The team recently released version 1.50, which includes a new weapon and some extra gear. They've got two of five sections of their main storyline finished, and the release is slowly rolling forward for completion of the rest of the story mode gameplay.
One thing I found interesting to learn is that, rather than push forward with the story mode, the development team listened to their playerbase feedback on their initial two episodes and went back to redo them, removing pointless fetch quests in favor of more story driven activities that actually added something to the game's lore. I respect the team for actively working to improve their game instead of simply pushing out more content.
I've sunk a few weeks into this, and I can reliably avoid starving or freezing to death on the default difficulty. I'm contemplating moving up to a higher difficulty setting soon, once I'm more familiar with the maps. While loot generation is semi-random, the maps themselves are all hand-crafted to provide challenging and rewarding experiences for each playthrough, and part of the slow, silent charm of this game is exploring the locations available.
Frankly, I'm in love with this solitude simulation. No other players, no zombie hordes, just man versus nature in a struggle to survive. Even just leaving the main menu open to listen to the blowing wind and birdsong is heavenly.
I highly recommend trying this game.
