Video Games are obviously not the same as the real world, but if you had the chance to exist inside a game's world exactly as it is within that game, within the timeline the game is set in, which game's world would you pick?
Keep in mind, this means the world you choose to reside in has a definite finite area of size. There are no patches of land outside of the area you can explore. Buildings, objects, anything you can interact with only function as they do within the game itself. If buildings are not enterable for the protagonist of said game, they are not enterable for you.
The only exception to this rule, for the purposes of this question, is that LOD/occlusion culling does not exist. You do not need to be within a certain distance to the player for the world to be visible and other NPCs to be spawned.
Other than that though, the world you choose must exist within your chosen game's setting and narrative.
So, what would your choice be?
