The story is a somewhat cliche "My best friend has been kidnapped" idea, but IO made the story so great that any cliche is completely irrelevant, and 47's soft side is definitely shown in the game.
47 retires from retirement and goes back to the Agency to do missions in return for collecting info on his missing friend, and these are some of the most unique, well planned missions in stealth history, basically Codename 47 quality with the missions and stalking your targets, with several unique ways to finish, such as disguising as a pizza boy, etc...
True to IO, this game is not without stereotypes, Russians wear ushankas or track suits, every Afghan wears a turban or openly carries an AK-47, fun stuff like that you just have to see to believe, and I praise IO for using such creative stereotypes.
The only issue a casual gamer will find is the difficulty, especially if you face a sniper, but you just have to be patient and not get too mad :)
After 117 screenshots, I recommend taking screenshots of every moment, it's a beautiful game, with sometimes funny faces to be found, trust me, you will enjoy being an amatuer photographer.
I am obligated by natural law to give this game a flawless 10/10, Jesper Kyd made amazing music, as well as the nice orchestra from Budapest, the gameplay is stellar and open ended, the story is amazing and will grip you until the very end, which even then leaves you desiring more for the future games, this game was amazing and I hope everyone gets to enjoy it.
