Better problem solving. Games with smart A.I. like Halo encourages the player to not run and gun, but take cover and use a more tactical approach to fighting the Covenant. Halo is like chess, each weapon is good at something, against certain enemy types. World history, games that take place in WWII offer accurate information, and I bet we all used that info to get decent grades on social studies quiz. Weapons, in Punisher 2005 written by Garth Ennis, who is well versed in guns, gives us commentary on what Punisher thinks of his weapons and his use for them. He makes witty comments, while also giving interesting information. It is also partially a reference to Punisher: The Armory, which was a book of nothing of artwork of guns and what Frank thinks of them. It's pretty educational!
