Considered it but I decided I don't trust the AI enough to make it's way to Sokoto. If possible I'll try to do it myself.GO Luxemburg!
Sokoto would be a good colony to start. Try to seize most of it before the Scramble. You should seize Zanzibar, if Portugal didn't annexed it yet
Danish colony might have been an option too since I was already at war with them, but I couldn't get any personal warscore and thus couldn't add any war goals.
