1. the ottoman empire or at least the portion that you created on the map was not an european power. in fact the ottoman terit that you have there is entirely in asia. so labeling it as a european power is wrong
Yeah we've been over this before. Turkey has always had ties to the European nations, dating back to roman times, and especially in this era, just before WWI. The Ottoman empire did extend into Europe through the Balkan Penninsula (although those territories are neutral for the sake of Gameplay). It also extends into Africa, through Egypt. Yes the map focuses on Europe and Africa but the Ottomans had their fingers in both pies so I think that more than justifies their presence in this map. Besides I need 8 European powers and The Ottomans had more African aspirations than the Austrian Hungary empire. True it's not geographically located with in Europe (which is a pretty arbitrary land mass to begin with) but do you really want me to write "European powers (and Turkey!)"
2. all colonizing countries must have the same flag backgrounds as the landing territories for easier recognition. i can say which flag belongs to what country but maybe others can't.
No they "Mustn't". I'll add the flag on at some point but not as a background. That'll make it confusing as to what African bonuses go with which nation. So long as the flag is present on the European terts. in some fashion it should be clear which landing points connect to which.
