Both of you are being a bit ridiculous here -- the other poster is pretending his opinion on Fallout 3 is objective fact, and you've got a very limited definition of depth.
A game doesn't have to offer narrative choice, or customization, to somehow be "deep". A story on rails can be an amazing game if the way you interact with it deepens your engagement with the story. (I'd say that's very much the case with ChronoTrigger.)
That's fair. I'd still bet that if you counted up the amount of writing and world building that went into Fallout 3 and compared it to any SNES RPG, you'd find dramatically more "worldbuilding" and "depth" in Fallout 3, but I don't have data to back that idea up, so it is what it is.
