Medal of Honor is like a really fantastic movie. The only other game I've ever played that has as strong a cinematic style as this one is Crimson Skies. The levels are very natural and convincing and the missions are well scripted and have a great sense of pace. And all the character of the game comes through without any real cutscenes. Apart from the mission briefings all the action and story takes place during play. It's too bad that this approach gives the end of the game an abrupt sort of ending but when people talk about good presentation, this is what they're talking about.
It's not apparent until you play through it a second time, but there's an awful lot of scripting that goes into this game. The same characters and situations that seemed so spontaneous the first time around suddenly begin to seem a little more predictable. The landing at Omaha Beach is a great example of this. As the individual soldiers run up the beach, they encounter the same situations and hit the same positions every time.
