Back then the cool library I found for developing games was Allegro for the DJGPP C/C++ development env for DOS. My brother and I started creating video games. It was so much fun trying to figure everything out and research things online. I seem to remember Yahoo kind of had curated directories of sites related to games programming.
My brother ended up working in the games industry for years, whereas somehow I ended up doing more web and data programming stuff. It pays better but sometimes I get excited about what it may have been like going the route of games dev. Ah, life.
