AC Unity is not the most technically advanced, it looks amazing but let's not forget how it uses pre baked lighting and pre bakes a lot of other things as well as has a lot of technical issues with LOD problems, all of which would automatically mean it is not the "most technically advanced".
I am saying a game can look great without being the most technically advanced by having good art direction and building around the limitations but it does not mean it is more technically advanced. Then there's the other thing about being hard to run doesn't really mean most technically advanced either. Most technically advanced would just mean how much of real time tech the game's pulling off.
There are some dynamic elements as well, cloud simulation affecting every aspect of the lighting on the environment including the lighting indoors drastically changing depending on where the clouds are outside of the building on top of having weather, crowd simulation for crowds of that size, literally every civilian having their own cloth simulation, it's doing a shit ton of things under the hood that I doubt many games are doing. I made a gif of a timelapse to demonstrate.
Consider that both of the building have interiors that are drastically affect by the lighting overtime and that clouds aren't always moving the exact same way when you load up the game.
I also didn't mention the AI of the npcs being simulated similarly to WD, outside of mini scripted side events like "kill the criminals," i've observed that npcs can
-randomly get into arguments in the street that may or may not lead to death depending on what they're talking about
-hold hands, and if the player were to say, get in the way and make them seperate, they will look for each other in a big crowd and make contact again, as in start to hold hands again and continue on their day
-"recognize" each other, stand aside from the moving crowd, have a long conversation, say goodbye, and then continue on their day
-randomly start celebrating and singing inside pubs
this extends to factions as well
-guards may have arguments with jacobins, which may or may lead to a fight between the two factions based on how much they were taunting each other, the same can happen to vigilantes who argue with Jacobins
1.If the player fights with and kills Jacobins, guards may intervene despite them being enemies with jacobins because naturally it's their job, they don't do this every time however, if the tables are turned and jacobins spot guards fighting the player, they will cheer the player on.
And this isn't even scratching the surface of the AI simulation. And as we all know, the game does all this while having a ton of graphical bells and whistles as well.
lol @ Unity.
The game looks really bad in play, only select screenshots can make it look good.
I'm gonna contest this notion with the following.
The interiors especially don't suddenly lose detail if the player moves fight ft away while standing directly in front. And there are a lot more shots of the interiors out there than the exteriors.
