I don't know why people keep automatically dismissing things based on possible settings. Science-fiction isn't always corny. Just because it's less likely to be handled properly, considering the mentality of most who try to handle it, doesn't mean every attempt will blow chunks.
Then again, World War II games are so godawful boring and rehashed these days, and Vietnam had such an anemic ending, that games based on those wars could hardly be interesting anymore. With one, any part of it not touched wouldn't make a good videogame. With the other...well, pretty much the whole thing wouldn't make a good videogame. So, I guess I can see where genre-hate comes from, now that I think about it.
I'd like to see a World War II game that doesn't try to span ENORMOUS AMOUNTS of the war's EPIC STRUGGLE. Give me one fucking character and his buddies to stick with over some shit that went down over a period of a couple of days, maybe focus on characterization instead of unbridled jingoism to make the NPCs interesting for a change (even CoD4, which was a step in the right direction by having NPCs with personalities, fell short of this.) Maybe even, gasp, tackle the horrors of war. Ace Combat 5 portrayed soldiers experiencing battle fatigue better than any WWII FPS I can remember. There's something bizarre about that.
And also, why is every war game these days so blatantly censored? I'm not expecting Saving Private Ryan with the shameless reality of what getting shot to hell and back looks like, but so we really need to be afraid of blood anymore? Maybe SOME dismemberment, just enough to remind you, hey, a fifty-caliber round does bad things to the human body?
NOT THE BEES! NOT THE BEES THEY'RE IN MY EYES
