I am a mechanical engineer in a day job and my passion for gaming led to this website. I enjoy games that have bit of a story depth and mostly single player. One of my favorites is Horizon Zero Dawn. I also dabble in multiplayer, but not battle royals, mostly because I am not good at it. Occasionally, I do enjoy trending survival games such as the latest Valheim and Muck. I have another website where I write more often VGNerdsAtWork.
