Screen capture of the Demonware blog entry.

On November 6, 2012, Kotaku reporter Superannuation (known for finding and publishing leaked information from the gaming world) published an article about an internal blog from a Demonware executive that was inadvertently made public through Google's search engine cache.

In the blog entry, the Demonware executive details a visit to Bungie on "Bungie Day" (July 7, 2012) during which he watched several presentations about and had the opportunity to play an early build of Destiny.

Although the blog entry was somewhat vague, the author did describe several things that made an impression on him. Excerpts follow below (click the screen capture, right, to read the full blog entry):

[T]he most impressive was a live scene walk through demonstrating lots of atmospherics, huge amounts of trees and foliage (SpeedTree), particle effects, dynamic lighting and dynamic time of day ending in a sun set. Also worth mentioning is that the audio team are working with Paul McCartney on music for the game.
This is not a dedicated server game, but there is some simulation and coordination running in their server architecture. The [multiplayer aspect of the] game was up and down a lot, [but] playing in a team of 3 we did manage to experience entering a zone to find other players already taking on the bad guys, it's cooperative so we helped out . . . before both groups went their separate ways. Which is a cool experience, making you feel like you are part of a much larger populated world.
At the end of the day I was excited about the game, I like the feel of being in a large world with different destinations and the interactions along the way. It actually brought back a sense of exploration I recall from playing [Elite] many years ago, although there was no opportunity to shoot aliens in the face in Elite. I'm not fully sold on the appeal of being able to change the colour of a weapon, but I guess it works in China, and customization and individual identity is a big theme for the game.
