Well...
http://en.wikipedia.org/wiki/Kushite
Without considering wikipedia as a master source, we can say that kushite faction is always forgotten in the classic area games. The only mod I know for now having them is De Bello Mundi.
It is an interesting culture, and they sure where not nabateans or sab'yn.
Without going in the allegedly "game" of the op, and even if I am really glad the new factions on EB2 where chosen that way, I must say I regret the numerous greek/hellenic factions in EB, compared to the numerous other factions that could have been implanted.
- Makedonia
- Epeiros
- Koinon Hellenon
- Seleukid Empire
- Ptolemaioi
- Baktria
- Pontos (semi-helenic)
- Pergamon
- Bosporan Kingdom
9 hellenic factions on a total of 28 factions... Almost one third of the factions is hellenic culture.
I understand the high role of hellenic culture in the area, but adding some, even if I will have real fun with them, seems to me those slots could have been used for other cultures.
Kushites, yes. But why not Belgae ? (Well, indeed there is a lot of celtic/germanic culture in EB2, I concede that point)
I mean... Kushites had taken egypt and was a great empire for some times, then loses but kept beeing a important economic faction in that area untill some AD time ! (out of the range of EB) They had their own alphabet, resisted the romans according to sources, and had prosperity, economic and military power...
So... I don't shay EB2 team should do it, but I say the idea is not illogical, in fact it could have been done.
