As for the value of it, surely history would be an important part. But also things like thinking spatially, math, timings, trigonometry, geometry, navigation skills, nautical knowledge, judgment, self preservation and lots of other skills. Not to mention computer skills if you let him install it and explain how save files and config files work and where and how mods are installed and affect the game. Also a better understanding of his computer stats and equipment and how it runs games. Something he'll totally miss out on should he only play xBox.
