In the early 2000s a couple of my friends from school and I decided to start a mod project, despite knowing nothing about how to make one. I don't remember much about it, not even its title. We made a webpage with a few details and our plans, but that's as far as it got. If I remember correctly, this type of thing was kind of popular among Half-Life fans back then. I followed a few other mods that never made it beyond a homepage with a plot and sometimes screenshots of a basic map or a reskinned model or something.
It wasn't until 2019 that I made an actual attempt at learning how to make a GoldSrc mod. So currently I'm still working on my first real mod, I've abandoned a few maps, but overall it's still alive.
