Snake has changed.
The Good: The plot is easier to follow than past games; Gameplay is actually action oriented; Well crafted cutscenes; Many many easter eggs; Loaded with customizable weapons; Great cast of characters; Outstanding visuals; Boss fights are fun; Bosses are hot; The PS3 no longer resembles a paperweight!
The Bad: Single player can be finished under 5 hours when skipping cutscenes; Multiplayer is present but poorly implemented; Soldiers can see Snake from across a warzone and call in backup; Bosses have no personality; Some voicework is cheesy; Dude, it ends!
