God of Kings
Ruler of all heads of state
I do not mean to use Polandball's graphics (apologies).You are all so easily satisfied graphics wise. Just look at the "civ visual novel" fanart of the OP. That's how it should look like, not like polandball (sorry, dear polish, no offense intended).
Basically, you would need lots of free time, permission to use the ip & a kickstarter of about ~10000$.
I meant that our version would be manga-style like Hetalia. The Polandball reference would be in terms of how it doesn't have a single author or illustrator.
