Sarcasticgamer.com : "Once you're past the 8 minute initial install (with more installs to follow at the start of each Act in the storyline) and you've chosen your difficulty, you're thrown straight into the defining icon of the Metal Gear Solid series. Nope, not stealth action, nor is it loud, all-out gunplay… it's that timeless little thing known as the cut-scene. They're back, bigger than ever, but at the same time they're better than ever.
Don't get me wrong, I'm not being ridiculously biased here. I didn't really follow the philosophical junk that Hideo (Kojima, head of the Kojima Productions development team at Konami and Metal Gear director) tried to mix in with the storyline either, and it became a bit of a confused mess. MGS3 players will have noticed the greater injection of emotion into the proceedings of the tale of Big Boss, and in MGS4 the prescription is even greater."
