This is why AAA title games no longer cut it. They always redo whats already been done, just bigger. A team of 4 created something refreshingly new, allowing a player(s) to not only do the usual sandbox exploration etc but become incredibly sucked-into its depth and rich world full of surprises.
Yes, this game can be scary but thats part of why its so good. It plays at your emotions and makes you surprised wanting more.
I can't say too much about the details as it will ruin it. You need fresh eyes for this game, no spoilers seriously. It might seem like a normal survival\craft game but you'll soon be running for your life freaking out and covered in blood (in a good way!).
One of the best games I've played in a long, long time. A real treasure in a sea of terrible games.
