Mouse, Metal Gear Solid was a game that held true to much of what Silicon Knights stands for, and I have always felt that it served as a "template" of what their games should play and feel like. By remaking Metal Gear Solid, they are working hand in hand with 2 of the oldest game developers, and they can't help but learn some of the greatest tricks of the trade. They aren't just making a fantastic game this time around, but they are learning scads of information on how to make their own games better. Blood Omen and Eternal Darkness are both excellent games, but they still felt very rough around the edges, and I think that collaborating with Konami and Nintendo so closely on this game will really help smooth out their own games.
That, and I think that the remake of Metal Gear Solid will go down in history as one of the finest games ever made. Silicon Knights really needs that boost to their name. Sure, we all know and love them, but the casual gamer doesn't.
