Enter Metacritic, a site that collects reviews on video games as they release and gives readers an average score. Through this, players are able to see what critics on all the biggest sites on the internet believe are the best video games of all time.
There's only one game that can claim to be flawless. Nintendo's Ocarina of Time isn't just the best-received Zelda, but the best-received game of all time. The story sees Link travel through time to save his home from the evil of his long-time enemy Ganondorf. Some major additions to this title, such as auto-aim and context-sensitive buttons, might not feel like a big deal to younger players.
Those features are everywhere now, but Ocarina of Time is the reason they exist at all, with developers realizing they should be staples in games going forward. Ocarina of Time was groundbreaking when it was released and it's still an amazing experience today.
