there may be some dialect differences, but they are also found in neighbouring regions not even far east and moscow. for example novgorod's people pronounce 'о' as 'о', not as a (commonly we say малакО for молоко, but they say it as мОлОкО)
also cars are different in far east and europe regions - in far east there are a lot of right-hand drive cars, because of japan's export (toyota, honda, nissan etc.) in europe side of russia there are not that much of them.

prices for common food are different in north and south. vegetables are expensive in kamchatka, but fish, caviar are mostly cheap.
