I agree with you. Both Zelda and MGS are the two best franchises in gaming. They are both games which the game designers (Miyamoto/Tezuka & Kojima respectively) pay so much attention to detail that it is astounding. Zelda:OoT was perhaps the deepest 3-D experience at the time and can even hold up today, while TWW was like playing a Disneyesque animated movie. MGS, on the other hand, is renowned for its detailed world. Each installement of these games always delivers in the gameplay dept. (aside from TWW sheer lack of difficulty ;p). These things, in turn, help to make these franchises that much better and memorable than a lot of the other franchises out there.
