What makes a game good?

[Wolf Kanno]

Well clearly you don't have a clue. :P

Just because people don't agree with you doesn't make them wrong, I figured you'd be smart enough at this stage in life to realize this, act your age.

A game is good if I have fun when I play it.

I was hoping for a more thoughtful answer, I'm asking about specifics, what creates the "fun" in it, is it story, mechanics, being able to do things you've never done, if it's the whole package what elements bring out the most fun for you? What initially attracts you to a game.
