I know it's damn late (game came out in mid-May) but I finished the single player recently and the game is too good not to have its own thread. This game is a monumental achievement in voice-acting and mo-capping (maybe not as much as Rockstar's last game, the lovely, mostly-brilliant LA Noire, but this is so much more action-oriented, it's amazing the work the actors had to put in). It's neo-noir at its finest, especially with Max's inimitable hard boiled voice-over narration. Gunplay is top-notch. The story, while a tad predictable to me, had enough twists and turns and genuine jaw-dropping moments (oh, Fabba!) to totally immerse me and be drawn into the Sao Paulo underworld.
Always had a soft spot for the first two games, but this one is pure masterpiece and should be played/experienced by everyone.
