It doesn't have to be extremely different, just different when it comes to architecture, values, and traditions.
That being said, I wouldn't mind an extremely different culture.
I just want new experiences and to be introduced to unique ideas, I'm sure I'm not the only one that seeks such a thing.
Here are some ideas for you:
Icelandic culture. Very old Nordic culture and ideas. Answers the question, how can an old culture modernize?
Finnish culture: Not Slavic, not Germanic, something in between or totally not the same. Very different perspective on the world. Sisu, coffee, no small talk, bizarre fun time rituals like the international "Air Guitar Championships".
Nigerian culture (s). There are several main tribes in the most populated country in Africa, and each of them has their own language, traditions, beliefs, clothing and building styles.
Australian Aborigine culture. Very different spiritual & cultural beliefs but not much in the way of architecture.
Of course, all cultures today have been affected by global media and internationalism, so the incredible anthropological discoveries of untainted cultures of the 19th and early 20th centuries can no longer be found. It's more about scratching under the surface of the internationalism to find the real gold...and that can be found almost everywhere!
