The other way in which games might converge on art is through the beauty and detail of their imagined worlds, combined with the freedom they give the player to wander around in them. Already quite a few games offer what’s known as ‘sandbox’ potential, to allow the player to ignore specific missions and tasks and just to roam around. (Many people’s favourite aspect of the Grand Theft Auto games involves their sandboxiness. A favourite sandbox activity in the California-set Grand Theft Auto: San Andreas was simply driving to the coast and watching the sun go down over the ocean.)
I actually did this in GTA4... it's... uncanny.
