Below is my Neapolitan Empire, as of 1621.
I am, as you can see, on the verge of completing my first game goal, to conquer all of Africa. Only the OPM Funj remain (I've left them alone until now because of their Orthodox religion and the stab hit if I fought them).
The enormous red blob is Japan, and the Indian blue is Vijayanagar. The lighter purple in Europe is my ally Lithuania, and the European blue is... well, I don't really need to say, do I? They've been an ally for most of the game, but occasionally decide to break it off or send me a call to arms...they usually come running back to me within a few years.
I've been HRE for a century, am about 95% Catholic, and maintain just under half a million troops, half of which were commissioned in anticipation of wars against Vijayanagar in the near future (and Japan in the more distant future).
My ultimate game goal is to wipe out the Muslim faith. This only came about when I realised I'd already converted most of Arabia, Persia, and North Africa already- it's not my innate genocidal maniac coming out. There are only 4 Muslim states left in the world, the OPM Sibir, two-province Kazan and the Ottomans, and the quite large Brunei.
