I gave splinter cell blacklist a B+. I thought the game was really good. Good graphics, good story, great controls and love the way they used the touch screen. Lots of content, plenty of side missions as well as daily challenges. My only gripe with the game was the broken multi player and lack of local co op.
Lots of bugs in multiplayer and most of the time was impossible to find a match, it wouldn't even connect online matches when I invited friends.
Still, I thought the game was very enjoyable and has good replay value. B+ in my book.
