This is not a question of getting older, it's been noticed as early as 2,000 years ago by Aristotle

Even though a study of story theory and realizing there are only 7 or so possible stories that exist, it would be a mistake to say that it diminishes the potential enjoyment of a story. In some ways, knowledge of it just makes a well executed story (Casablanca, Star Wars) that much more astonishing and enjoyable.

Personally, Fallout 3's appeal was not in the story, it was in the setting and world at large and getting the chance to exist and scavenge within it.

Yooouuu want some more?

Well the incorrect part wasn't to stop playing, from the sound of it his son was owning him 1v1 for a half hour and was relentless and had no sense of good sportsmanship. There's no opportunity to have fun or improve in such an environment.

It would be like if your son was a college football linebacker, and you wanted to toss the pigskin with him in the backyard and all he did whenever you had the ball was hurl himself at you, knocking you to the ground, breaking a few ribs in the process, then running straight to what he figured was the endzone, then kept repeating this despite your pleas to go easy on you. His son was being rather immature even for a 17 year old.

BUT

That doesn't excuse a father calling his son names and declaring he'd never play with him again, all over a video game.

The correct response is, "Gee, that's all for me today I think..."

Then when he's in school, you fire up Xbox live, practice at the game for a while, learn the ropes and learn some trick in a nice competitive environment, and then challenge your son to a rematch now that the learning curve is overcome (if he played Halo 2 how long could that possibly take?)

So yeah, a bit of bad parenting there, but also an immature kid.
