This is absolutely the best game I've ever had the pleasure playing.
The storyline is quite engaging, the fact that you are required to gather, mend, heat up your food, take care of your health and outerwear, to survive, makes it far more interesting than just killing and running, like what most games these days offer, unfortunately. It's also quite peaceful and remedial, and despite the average graphics, it feels very real.
Though, I have to say, episode 3 was a little short, felt like it was rushed, so to be over and done with, just tick the box...
If you could build structures, it would definitely be a nice addition to the whole experience, but as long as it doesn't become monotone and repetitive, such as game "Forrest"...
I can't wait for the remaining episodes to come out.
