Let's starts with the obvious, the game is beautiful with an unique artistic direction. Right at the beginning until the end, the immersion is total. The music and sound design are also really kicking in, with nice moment of music and cinematics well executed. Voice acting is great with the same voices (french here). As for the story, it's good, not as simple and predictable as you can think when you begin to see where the game is going and all the characters are well written.
You will not travel as much as in the previous games, but that is okay, because all the effort were but on creating a rich and credible city Vaghen, and it's surronding, where most of the game will take place. Build smaller but better basically. You can see all the love the dev put in the game.
The gameplay is like any point and click and the puzzle are quite simple, way simpler than before. That i enjoyed because i was more focused on the story and less in solving riddles.
Some blackspot : some moment are rough meaning that the writing could be more demanding. For example, a wooden table isn't a credible shield against a machine gun. etc.. but nothing dramatic. I also had frames drop, so the optimisation could be better. And finally, the camera rotation is not helping especially in small places.
If you liked the previous syberia go for it. If you don't know the games and don't want to play 3 games, (i myself didn't even finish the third, too many bugs) i think you can stil play it. This is a new story, even is there is element of previous game. There is a resume available si you will not be lost.
