Then I would like to complain that many cultures cannot be founded in their real geographic locations because of the lack of required resources and sometimes even terrain. Here's the list of what I've found
Ainu: No Furs on Ezochi/Hokkaido. I would suggest one of 3 solutions:
1) Add another tundra tile to the island and give it Furs resources.
2) Replace Seals with Furs.
3) Bug the mod creator(s) to change required resource for Ainu culture.
Will take a look into this area, might change it to furs, thought you could get furs from pelts, but I'll see if I change move some things around.
American: No Cows, but maybe those can be transported from Europe later? Haven't reached that far yet.
Pretty sure the Great Farmer can do something about this, cows were domesticated in the Old World, Egypt I believe was the first place, but don't quote me, most of the domestication of plants and animals happened in the 4 great river areas.
Mesopotamia, Nile, Ganges rivers, and the Yellow River.
Aztec: No Obsidian in southern Mexico. There's a couple of unused hills south of Aztec starting location.
Okay, I need to sprinkle some obsidian deposits in Central America.
Benin: No Wheat in West Africa. There's one coastal grasslands or lush tile that could give Wheat.
This I can easily change.
Brazilian: No Coffee, but maybe it can spread from Ethiopia later?
Pretty sure it can spread... Great Farmer I believe.
Byzantine: No Iron anywhere near. The closest hill on the Balkans is a good spot..
There is iron in Anatolia, near the Hittite start. So spread into the Carpathian basin, and conquer...
Carib: No Coconut Plant terrain feature on Caribbean islands.
Can do. (I think they are changing some terrain features to actually resources in the SVN though... I think)
Cherokee: No Pumpkins, but Apache do have some close to their city.
I'll take a look at the region.
Goth: Rubies? What were they thinking? What do Goths have to do with rubies? Maybe some legendary ornamental weapon decorations? Still, there were no sources of rubies in Europe. I added some just to have Germans with Goth culture in my game, but this should really be changed in the mod.
I'll be honest, I never understood this, mainly because rubies are literally from certain areas in the world... and I didn't bother stretching the truth just for the sake of the Goths. I did some good research on the gem replacements when I looked through it.
Greek: No Marble in Greece? All tiles are taken up , but one can be added north of Athens without connecting to any islands or other landmasses. Alternately, you could just replace on of the two Stone resources with Marble.
I might as well do this... I haven't touched any of the basic resources that have been there from the original GEM.
Hausa: No Dye in West Africa.
Can you cite me some sources that shows that West Africa was a source of dyes?
Hittite: Closest Cows are more likely to be taken by other civs. There is an unused grassland just NW of their starting location.
Go do the Hittite thing and conquer those silly civs.

I'll take a look though, and I'll probably put a cow in the region... possibly.
I think Apples should be for the Hittites though. Or horses.
Holy Roman: Incense? Not a very logical requirement, but the resource itself is very strange as well. Anyway, doesn't make much sense as a culture. Should be more like a wonder that requires German culture or something like that.
Should require the German culture of some sort, or Roman... but I don't know why Incense which hails from the Middle East.
Indonesian: No Pearls close to main Indonesian islands.
Thought I put some in the Indonesian area. Around one of the Indonesian islands... pretty sure. If I'm wrong I'll tack in some pearls for the region.
None in the desert nearby?
Kanem-Bornu: No Diamonds.
Is this an African culture or Oceanic, my brain is not functioning at the moment due to so MUCH awesome...
If Africa: Lots of diamond in Africa. XD
Oceania: Cite me a source that puts some diamonds in its respective area.
Kongolese: No Prime Timber. You can add some in the closest forests to the north and to the south of their starting location, so they get the culture whichever way they decide to spread.
Kongo has many jungles, I'm sure I can tack some 'Prime Timber' into the area.
Maori: No Prime Timber on New Zealand, but a lot of space for it.
Will do
Mapuche: No Wheat in South America, but a lot of space for it.
I'm pretty sure there is no wheat anywhere in the Americas, so this is a resource you need to bring over from the Old World...
Old World has Wheat, Barley, and Rice... New World has Potatoes and Corn.
Minoan: No Cows on Crete. The only solutions are to either place it under the goody hut or expand the island one tile westwards.
I think I decided not to do this in the end as I came across the same problem earlier.
Moroccan: No Spices in Morocco and I wouldn't want them so close to Europe anyway
.
Maybe... one tiny spot of spice... but I really don't want to give too much to the European theatre... I can easily steamroll an Empire when you start bringing it under one rule.
Mutapa: No Gold in Zimbabwe. There really should be some. That was a mother of mother lodes.
Cite source, but I tend to agree, and it shall be done.
Polynesian: Same as Carib, no Coconut Plants on the islands, and very little Fish.
Guess I have to look up where the coconut dervied from, but even so I should sprinkle them in the carib and polynesian islands anyhow.
Roman: No Olives close to Rome. The closest are on Sicily, but they are more likely to be claimed by Carthaginians. I suggest putting some in Northern Italy as surroundings of Rome are all full.
I think I forgot to do this actually, as I wanted to do it before I believe.
Somali: Don't see any Hemp in East Africa. A lot of space on the Horn.
Will take a look.
Swahili: No Fish along the coast of southern East Africa. Absolutely no sea resources there at all.
You are probably, and most indoubly right and I should probably sprinkle some along the coast.
Tupi: No Squash in Brazil.
Hmmm, will take a look into this.
Vietnamese: No Grapes in Indochina.
Probably not going to happen unless you bring in a Great Farm... that and Vietnam is bloody rich as hell. XD
Welsh: No Clam off the coast of Wales.
I think the Welsh need a diffferent requirement... like Celt, hills, coast and a hill. (Grassland though)
Zapotec: No Gold in central Mexico, but there should really be some. Same as Zimbabwe.
You know... you're right... I also need to check if there is Silver in Peru while we are talking about precious metals.
