I agree with ya to a point, but when in development things never turn out the way one plans to. Things change constantly, they get cut or they go in a new direction. Preproduction and the actual development never really match up fully. What seems cool initially once implemented it either doesn’t work or you get push back because it isn’t “what it should be”.
Best showcase for that is halo 2, the technically made two iterations, first one got scrapped entirely and the second final one had many things removed in order to meet release. In an old interview with oxm Bungie stated they were gonna out in sprint because it’s what they wanted since the ce, but in a most recent stream a dev said they got push back from the qa/testers saying sprint “wasn’t halo”. In the videos included with the se of halo 2 I think it was joe staten or the other main halo creator that stated they removed tons of stuff…and I lost my train of thought, blame my dog, she wanted scritches.
Anyways, things change so they can’t start feeding info until the narrative of the development is definitive, or near it possible.
