Actually, i won't link it here, but there are websites that do a pretty verbose (and sometimes very stretching) job of relating Star Wars to WW2, and there's alot of stuff that is just blatantly ripped from history too.
.. but that's enough off-topics.
TBH, I'd be pro-slight-sci-fi for WW2. i think it'd be fun.. "realism".. well duh no.. but fun anyhow :]
