This is one of the few games that have very little wrong things going on, except of some vehicle section that drag waaaay too long for their own good it's a perfect game.
Good pacing, amazing set pieces, solid gunplay, great atmosphere and story. It kinda feels like the game was some test of the new physics engine but it's a damn good videogame as well. It also expands and improve every single aspect of the previous game.
Overall an amazing experience that still stands the test of time perfectly and should be played by everyone.
