What's your favorite game of all time?

Question is pretty simple;

What's your favorite game of all time?
Feel free to add a screenshot and to explain why it's your favourite.



I bet a lot of you already know which one mine is, but...

GTA San Andreas

Why?

The world (country, desert,...)
The MP
The feeling the game has

 

[GPow69]

Portal 2, for sure.

 

[Stybar]

Portal 2, for sure.

Seconded.

Although I also liked Need For Speed Most Wanted

 

[Panki]

Best atmosphere I have yet experience in a videogame.
Incredibly nice graphics and leveldesign, epic soundtrack.
End of story.

^ I used to play that on my PS2 (1 or two, can't remember)

Was an epic game indeed :3

Duke Nukem 3D was pretty epic :3
