i tend to agree with the original aesthetic of the halos, because it fits with the feel of "technology-hidden-in-the-rock" that i get from the other games. as far as i know, no one is planning to remake Halo 2, so how will they reconcile the look of Alpha Halo to that of Delta Halo? The covenant may not be innovative, but i don't believe they had too many artifacts to go on on their home planet, and therefore had to reverse-engineer some things or perhaps re-purpose other tech meant for other functions. the covenant seem to favor the appearance of power, which is demonstrated on their ships, weapons, and armor; the overheat and power indicators on the plasma weapons, the exposed shards on the needler, visible power conduits and generators aboard their cruisers and on their ghosts and tanks. The forerunner based their architecture on "radical, specific energy-based matter/energy/space distortion and redirection" underneath inconspicuous buildings and monuments. nothing exposed, nothing visible to the naked eye or precursory scans. very covert. something the covenant are CLEARLY not.
