I just idly clicked the latest Sakurai/GCCX collab video and was not expecting Arino to lead with a question about friggin' Densen https://www.youtube.com/watch?v=zfh0oq-_nJQ
for context, Densen was a game announced by SCEJ as a PS2 launch title that never came out and barely existed beyond the little public footage that's out there—it was being led by Kiyoshi Sakai, creator of the Umihara Kawase series, and when I asked him about it years ago, he told me that Sony forced the team to show it off way before they were ready and that they were never able to figure out what it was they were actually trying to make or how it'd work, hence why it never released.
Even so, despite basically living and dying as a single demo reel, it's a game I've seen cited more than a few times as being influential or inspiring to those who saw with, most notably by Keita Takahashi, who says it was a direct inspiration behind Katamari Damacy... not because he played it or knew how it'd work or who was behind it, but just because it looked neat.
(spoiler: Sakurai had no idea what he was talking about)
