In reading fan-produced essays such as those of the blog "Ascendant Justice", it has come to my attention that some fans have hypothesized that "Halo 3: ODST" was developed as a 'fulfillment' of promised innovative, open, fast-paced gameplay; in point of fact, the aforementioned site dubbed "Halo 3: ODST" as "the Prodigal", citing the E3 2003 demo for "Halo 2". Was this kept in mind during development, and what other overall visions - or goals - were set for the final product?
