In Splinter Cell:Conviction, Third Echelon's Grimsdottir launches Sam Fisher on his final mission.
Splinter Cell:Endgame introduces newbie Ben Hansen and his Delta Sly group as Grimsdottir, closely watched by a traitor in the NSA hierarchy, secretly directs and delivers Hansen's ragtag team to Fisher in support of his final mission.
Interestingly for us, some creative folks stepped outside the box here (author, publisher, game developer, come quickly to mind), and gave us two independent books about the same mission as carried out by different characters. The clear distinction between the two books is the actions of a loner versus the dynamics of a team with all their conflicting shenanigans. I catch the old versus new message - call it an attitudinal variation on the old glass half empty-half full metephor.
A weary Fisher contemplating the settlings in his glass. The young and energetic Hansen eager to fill his to overflowing. In the middle, Grimsdottir, a realist, who knows that, either way, somebody in Third Echelon will be there to wash it.
Endgame works for me... big time.
