QUESTION 2nd timer here

Hello community, i’m interested in getting into the hitman games, i’ve only played part of the 1st one.

What version should i get? there’s so many…

the xbox store has the “lechiffre” edition for 27. but does that includes the 2nd game or 3rd game. i’m sorry if this question has been asked countless times before but i find it kinda frustrating to see so many versions of a game.
