[quote][b]Posted by:[/b] BestSpartan117 it was scripted but super awesome.[/quote] Then the demo did what it was supposed to back then, build hype for Halo 2. Bungie knew that the Xbox wasn't capable of producing a level like that - "The graphics engine that we showed at E3 2003, driving around the Earth city... That entire graphics engine had to be thrown away, because you could never ship a game on the Xbox with it," said Chris Butcher, engineering lead on Halo 2. "We were building stuff that just couldn't be played, in any engine". ([url=http://www.eurogamer.net/articles/bungie-halo-2-e3-demo-was-a-fake]Source[/url]) This pretty much supports the idea that it was just for hype building. Granted, it showcases Bungie's ambitions for Halo 2 at the time and they did deliver in the final product on all the mechanics that were shown in the E3 demo. However, as said earlier and correctly pointed out by Sliding Ghost, the whole demo was scripted. They had to follow set paths for the whole demo to play out. Specifically, look at the part with the Warthogs, they are clearly following a set path rather than dynamically driving like in the final game. Nevertheless, the demo was still impressive.
