Glance over the videos of Metal Gear Solid 4 - and there have been plenty, including the hilarious new Tokyo Game Show addition - and you might be given the impression that it's a complicated game full of fiddly little controls. That's certainly how it looks when Kojima acts it out. Fortunately, it's not how it plays. In fact, judging by the playable demo here in Makuhari, it's gone from being slightly awkward to deceptively but welcomely simple. And let us not forget that it has a monkey in it.
