Wow. In my own gaming experience, Ocarina of Time is the greatest game ever made. In 1998, Link was riding a horse around a living, breathing Hyrule world. That set the standard for building a streaming game world. It wasn't separated into levels (e.g., Super Mario 64). Nintendo introduced the targeting-lock system of combat to address 3D camera problems. The game featured elaborate in-game cutscenes. It transitioned everything from the SNES Link to the Past seamlessly into 3D without making it feel like a platformer. To me, this was the first sandbox game too...with all of the side quests and collectibles.
