The only records he ever owned were The Best of Acker Bilk, and a load of war movie soundtracks. He only ever seemed to watch war movies on TV - by association I became deeply familiar with The Great Escape, Where Eagles Dare and The Guns of Navarone, and sort of absorbed a ton of info about the war just because it was always around me growing up.
Even now for Christmas and birthdays I only ever buy him books about World War 2 because, frankly, there's no point getting him anything else. I'm amazed that people can still find new things to write about the conflict, but - I guess - it was a big old war that went on for six years.
Unless you're American, of course, in which case the war didn't start until 1941.
As is too often the case, CoD: WW2 tells the war from an American perspective. An English bloke pops up at one point, and a member of the French resistance becomes the focus of one mission, but for the most part you'd think it was a war fought exclusively between the Americans and the Germans.
Maybe if the game had been a bit more inclusive we would've seen a less predictable selection of missions.
