What makes a good game?

We all play (or did play) RuneScape. It is clearly a good game from most of our perspectives, at least in some ways. But what really makes a good game?

Obviously there are various categories for ranking how good games are;

Experience (Graphics/Sound)
Storyline (if any)
Challenge
General Gameplay
Addictiveness

Which of these do you think is the most important, if any of them? What do you think really makes a good game?

I think game length makes a good game. Look at Fable, a really awesome game but it really short. Look at runescape, they have been able to take a simple game and make it playable for 5+ years...

Definitely general gameplay. Why do we even play games?

Is it because of the graphics? No, if the graphics are incredible but the gameplay is abysmal, then the game would NOT be fun at all.

Is it because of the storyline? Eragon (The game) may have a solid storyline, but it has terrible gameplay, which lowers its rating dramatically

Is it challenge? If a game is hard, newbs won't play it. o.O

Is it addictiveness? I'm sure people won't want to spend their life on a game...

Constant updates are essential for things like RuneScape in order to kep older player interested.
Free will - I hate games where you have to do this one thing, then move and to do another, and have to keep going in one line. In RuneScape, you can do whatever you want.
Suitable for all types of people too. It has to keep 9 year olds and 30 year olds entertained, as well as males and females.

I'd say addictiveness and gameplay, a game doesn't need graphics or a storyline to be good.

Take Doom for example. The graphics sucked and there was no storyline but it was still fun to play.

Many internet games like Copter and Curveball are fun to play, neither having good graphics or a storyline.

What makes a good game?

There's no real answer. It all lies on the perspective of one's view. Some like graphics, some like gameplay, some like the storylines...

For me it's basically:

-Gameplay.
Good gameplay doesn't mean complex controls, with many features. Look at the first Final Fantasy for the NES. It only needs two buttons, with simple functions. A for Accept, B for Cancel. That's it. Yet the game is so great it saved Square from bankruptcy.

-Tricky situations.
Ever got stuck in a videogame, because you don't know what to do next? You probably wouldn't have that happening in the new games nowadays, because what you needed to do is like laid out for you. Back then you had to sit down and think what to do to get to the next part of the game. Come on, how many of you got stuck at the last few parts of Final Fantasy because you didn't know you had to use the LARP from the first part to open the gate to the final part?

-Good ol' cliffhangers.
Gets us want to know more. So we buy sequels. So the company gets more money. We get happy, so do them.

-Storylines.
No way man, I don't like the old "Save the world" storyline. What I like is a storyline with suspense that gets you thrilled and want to go on the game to know what will happen. It sorta gets you addicted. Not really needed, but with the new games out, we need more originality rather than "A town is infested with zombies, kill them all and come back alive" Resident Evil games.

-Graphics.
Only to a certain extent. I don't like 8 bit graphics much, but I appreciate any game with decent pixels or 16 bit graphics. As long as I know what the hell I am. How many of you were confused to what are you when you played the Atari or Commodore 64? Do you even know what they are?
