Played 100's of hours and keep coming back. Like the increasing scale of difficulty as you get farther out. The rewards will sometimes force you into an aspect of the game you have been ignoring.
A fun concept. Whatever you can fit in your baclpack is what you have to fight with. Figure out a balance between permanenet and temp items to achieve victory. Some runs you are unstoppable and some you barely sqeak by.
Combat is tough at first with every fight a potenial loss. But you learn more about the mechanics and how they work and it becomes chalenging rather that leathal.
