Expectations from the game (Metro Exodus)

I believe that the game takes place after the book Metro 2035, and that all of us want beautiful and unique story, to the story of Artyom, ended successfully, so in the end it was all clear and had no issues (As it came to me after reading the book). But also improve the intelligence of the AI, stealth gameplay well to convey the atmosphere of the world (As it was in the last parts of games), Large and varied levels, that there is less linearity and a bellboy (As in Bioshokc), the opportunity to choose any kind of plot effect, and this effect would later on the story, more weapons and upgrade for him, more horror and mystery, well... Different stuff, which perfectly complements and diversifies the game, for example: wiping mask, burn the cobwebs, wear, blade and breakage of the weapon (As it was in FC2) and its upgrade during the game (Like in Crysis), well, etc.
What do you want to see in the game?
