What is your idea of the perfect video game?

Describe it to us.
Mine is like this:
The game starts out in the stone age, with development of your civilisation through the ages, like the Empire Earth series, with the city building complexity of the Sim City 4, the strategic scale surpassing that of Supreme Commander, expanding it to a global scale, while always having the option to control individual units from a first or third person perspective on the battlefield. Once you reach the space age, it should be a mix of Galactic Civilisations and Sins of a Solar Empire set in a fully 3D universe, where stars are scattered through all 3 dimensions, as it was done in the space age of Spore and not just in a plane as with most games. And I want the ability to control individual starships and fighters as well.
All of that with superb graphics á la Crysis.

And now I am depressed, as I know such a game will never be made.
