The term "pwn(ed)" was popular before any of these games existed. Here's a much more thorough history lesson, linked from HIBP itself: https://www.inverse.com/gaming/pwned-meaning-definition-orig...

"At this point, pwn allegedly meant to demote or dethrone someone, but the slang was quickly picked up by early computer-users that exchanged messages on FidoNet, a system created in the 1980s for exchanging emails or text on digital bulletin boards. This is where pwn slowly transformed into the insult we know today."
