With the arrival of Spec Ops: The Line it seems as good a time as any to examine the ways in which literature and video games mingle. No, this isn’t an article debating whether the writing talent of the Yager Development staff could come up with a better title that Shooter: The Bland, but rather the ways in which video games differ from the literary counterparts that inspired them.
What about the Elder Scrolls games? Deecent book reading.
Really depends on the game though as if it has a place , I mean some games really don't need such depth and are intended to be purely action and such depth would just get in the way.
I think it really is a case by case basis.
But it shouldn't be thrown into everygame but for RPG I see no reason to not have them in there.
