Really? What’s the most recent video?
And in my opinion, it is, in a lot of ways. Even though we were given the City Scene and Lyra (and VOA), none of them are actually as technically impressive as LON. We have massive cities and crowds with ray-tracing already (the newest patch of cyberpunk 2077 calls that to mind), and we have high-quality shooters and open-world GI. LON was built with a level of visual detail and fidelity that no game demo thus presented has carried in the same way.
More than anything else? LON is simply cooler than all of the other demos. It is visually and artistically spectacular, and it’s the fullest representation of what the next-gen could actually achieve with the time and detail put in, not to mention the incredibly dramatic destruction sequence at the end, which no other demo really matches in size and scope. At some point, I’d like to see it released, even as the mess of beta blueprint code and kludges it probably is. Although this may be an overstatement, I think it will be remembered as a part of gaming history.
