I agree the gameplay has drastically altered from the first games to now. Way more RPG-esque with levels and stuff.Alright, fair enough, maybe that wasn't my finest moment.
That said, my point still stands.
The games don't really look like Assassin's Creed anymore, and the past few entries have barely even touched the Assassin/Templar conflict, and with the whole gameplay revamp of Origins and beyond, we are left with games that don't look like AC, don't play like AC, and barely even follow the same plot.
So, I ask then, what is the point, other than brand recognition?
It just seems like the newer games are so desperate to distance themselves from their own franchise, that we don't even have a game that really resembles where the series came from. I just want Assassin's Creed back, dammit.
As to your overall question of "but why?" I can only speculate, but here are my thoughts on it.
First, the last several games have all technically taken place BEFORE the iconic look of the Creed happened. AC: Origins was heavily implying that the various outfits, with the hooded motif, in that game, were the origins ("That's the title of the game!" Screen Rant Pitch Meeting Guy Voice) of the classic elements. So you could say it's not been canonized yet, between Origins and AC 1. But I felt that I was wearing a "brand accurate" costume with most of the looks in Origins. Odyssey, not so much.
Odyssey hinted at the warring factions, or at least the proto-groups that will eventually evolve into the Templars and Creed. I think, they are trying to do a soft reboot, of the various elements of the storyline, and stuff, because it started getting cluttered. Frankly I think they are just trying to dance around a lot of the story elements they've painted themselves into, with the entire franchise being nothing but an extended flashback sequence for a present day crisis that they forgot to actually flesh out and make interesting. A crime in my opinion, as I was always more interested in the present day stuff, and thought the film was actually GOOD (Yeah I said it, fight me!) because it focused on that storyline, and left the flashback stuff to just a few minutes of time. But anyway.
I do think that you are somewhat correct, that a lot of the whole "sticking with the hoods" plan, IS brand recognition, as that does have a powerful impact on sales. And frankly the look is pretty cool, regardless of color scheme.
