Did you research any other West African countries for inspiration?? Or did the idea of basing K'Sante on Ghana come early in the development?
The team wanted to create a West African-inspired champ from early on, and Ghana was chosen very early. West Africa isn't a monolith of culture, but there's some overlap between some of the countries--especially considering much of the modern borders in Africa were drawn by white European nations and ignored a lot of the differences between different groups of peoples.
They did look at the region overall, and highlighted a lot of the regional traditions, but tried to stick closely to Ghanaian inspirations.
