Intrestingly, the very earliest viewable message on the PSA discord is from 01/22/2026, predating the first instance of House Party.
"The issue I was left with was… what do I even update PSA with? Briefly, I considered what is now going to be BREAK-OUT. But none of the concepts I had were developed enough to really work, and I wanted to get the site out soon. Skyblock was another idea, but the art for most of the pages was too shitty for me to really consider. ... That left the obvious option - House Party. So I quickly threw it up on the site, and it’s been updating almost daily since."
It's possible that the server was initially created with a different purpose in mind.
