It was Halo combat evolved for me. My dad didnt give 2 shits that I was far too young to play it. The level "343 guilty spark" is probably why Im rather fond of horror too
N64 Diddy Kong Racing and Pokemon Red were the first games that I played like a degen. Earlier than that, I remember playing the original Doom and Wolfenstein when they came out
I actually don't know what the first game I ever played was, or what hooked me on gaming. My parents had a win 3.1 computer when I was barely old enough to associate a screen with a mouse and certainly not literate yet, and I've been using computers ever since.
It was probably something in the Best of Windows pack, like Chip's Challenge - I still remember being frustrated beyond measure on some timed ice level.
