Hi! Thanks for this, hopefully we get the chance to revamp the Horn of Africa and certain other parts of the continent that are close to my heart at some point
(But I make no promises)
One thing though - a large part of the work in making new idea sets is coming up with convincing flavour texts. I appreciate the explanations you have given for the ideas you suggest (it is really remarkable how many people suggest ideas and think that a title and a bonus is all that is needed), but you really can't go overboard when proposing flavour texts. (Well, ok, you probably can, but it is always easier to cut stuff than to add things where there isn't enough). Here's a thread that did it particularly well.
