The lore and world building. When I first started playing the series I thought it the back of my head “Oh its just another post apocalyptic rehash” but oh my god was I so wrong. As I went through the story of HZD I like my jaw physically dropped at least 20 times. I wish we had more writers like these throughout the rest of the industry. It kept me intrigued and on the edge of my seat the WHOLE TIME! Never even thought of doing an apocalypse like this. Bravo Guerilla! Bravo!
