Of course it is the best console ever. It stands on a podium in my room and even when I go through phases of other systems I still look at and celebrate the King every day. But wow @ people who think that PS4 has chance at repeating the success of PS2 - it simply isn't possible because a lot has changed, the world has changed - games take more time to develop for various reasons, there isn't much room for innovation anymore, people are tired of buying and playing the same game over and over etc etc.
Deus Ex (2000) - a game that pushes the boundaries of what the video game medium is capable of to a degree unmatched to this very day.
