I wish all Civ V modders could continue on Civ V modding, while I will be putting plenty on time into it, I just don't think I'll even remotely like Civ VI as much as I love Civ V, and that's just the game itself, not even taking modding into account. I know it's over done, but the graphics are a turn off. Civ V's was and is the best for the franchise, especially to represent a strategy game, that most certainly should be serious. The leaders is a whole other can to talk about, let's just leave it at "meh" at best.
Back on topic:
Kenya
Kosovo
South Korea
Venezuela
(The) Hui
Timor-Leste
Israel - Ben Gurion* Though confirmed on it's continuation
Angola
Costa Rica
Egypt - Nasser
Greece - Venizelos
India - ???
Indonesia - Sukarno
Kuwait
Luxembourg
(The) UK - Margaret Thatcher
(The) US - Ronald Reagan
Ghana
Were the main ones I wanted to see get done and even add to my collection of civs/alternate leaders that I want in Civilization with save Luxembourg and Timor-Leste as I am unsure about them and Kosovo I was interested in seeing it. Not that the others were uninteresting in any way, shape or form.
