Looks like your regular modern AC game design, you either like it or don't I guess...
I personally cannot play these games anymore, but it's not just ubisoft, it's this type of open world in general.
Showing all the points of interests before you even explored the areas really kills a lot of the interest to me.
It removes a lot of the fun, because it doesn't feel like exploration anymore, and more like just going from tasks to tasks, instead of finding things on your own while exploring a world. The fact that it's also always the same type of activities that are copied and pasted everywhere doesn't help.
Another thing I really hate in the modern ac games is the leveling system.
It's designed in a very strange way that feels kind of... fake? If you're let's say level 10, trying to fight a lvl 13 will be almost impossible, even the most basic ennemy will feel like a huge boss, requiring 10 minutes to kill. But if you lvl up just one level, so now there is only 2 level of difference instead of 3, it's suddenly a LOT easier and faster.
I never understood this, it doesn't make any sense because going from level 10 to 11 really doesn't change much in your stats, but it seems like there are some kind of hidden stats somehow depending on the level difference between you and the ennemy... It makes the whole RPG aspect feel super artificial.
Valhalla was really the worst though, because here I really don't know what was the point of the RPG elements. In the options, you can directly decide how % of damage you deal, if you want to instant kill on stealth assassination, how % of damage you get etc... Wtf is this? It feels like having a built in trainer / cheat system for your game, but that's directly in the options.
Because of this, it's super strange because you don't really know how you're supposed to play the game really, what's the intended way? But it seems like there isn't any intended way, it's a bunch of random things so that "everyone can enjoy the game", but because of that, it's a game for no one, and it feels boring and pointless.
I somehow still enjoyed AC Odyssey, because of the world and how great your character evolution was with all the abilities etc, the DLCs in particular were great, but most of the issues I mentionned about the leveling and open world design were still present.
I imagine most of my complaints will still be present here, and another thing that worries me is that apparently there are a lot of historical / reproduction errors, which is a shame since AC games were usually pretty great for that, so it won't be the same if here it's more like a badly recreated fanfic japan. (I might be wrong about that, it's just some stuff I saw in videos, japanese people talking about the environments, architecture, armors etc...)
