Teeworlds. When I was a kid I searched up “free online multiplayer games on pc” and it actually led me to this Wikipedia article full of open source games. I tried out teeworlds and I was hooked on it and it led me to playing other open source games like cube 2 and open arena. In my head, the term open source meant “free stuff”. Searching for open source stuff led me to discovering Linux and trying it though the Wubi installer and eventually moving to it a few years later.
I have seen this same image circulated for years. We need a new one because transmission in D tier is unacceptable.
