thats one possibility, it could be interesting designing a campign around "the battle of crimea".
-like you said, water-borne landings (nothing like d-day of course, crimea much more shallow then the english channel
)
-and the liberation, retaking of sevastapol could be interesting.
like double deuce said it could be some time before we narrow down to a particular area.
I think the limiting factor as the "german baised?" general consensus showed would be finding maps and information on the area. not to say certain areas would be "impossible".
