When I first played it, it was about five years ago, the game was like a breath of fresh air. Huge rich world. Freedom of action. Lots of all sorts of “goodies” in the form of searching for all sorts of fragments, etc. I especially liked just climbing all the buildings and running across the roofs. The game introduced many features that are now used in new games. For example: Our favorite “towers”: climbed - updated the map; etc.
It was interesting to move between eras. It was like: you were tired in the Middle Ages and went out to “smoke” in modern times)
Sometimes there were difficulties with parkour and the camera at these moments. On some missions I had to suffer.
Recently I tried to go through the entire series in one fell swoop and came to the conclusion that the first part is the most atmospheric, and with each part the game loses a piece of itself, turning into a “conveyor belt”
