Castille/Spain in 1590
Started by eating northern Italy, Flanders, followed by portugal thanks to the excommunication casus belli and ending up facing off with england against a united france.
Luckily I had the technological lead and was able to time the war so that my newly minted Condottieri faced off against lesser but more numerical and better led troops. After a tricky first war France were reduced in two more excommunication wars to the small inland stub ready to be absorbed into the growing spanish empire.
On the meantime the americas were being madly colonised, with an average of 20+ colonies (once I could afford it) being maintained simiultaneously to try and successfully shut out england from the americas.
Great Britain eventually turned to africa to satisfy their colonial urges, but they happened to neighbour my previous conquests of Songhai and Mali so after a brief debate they were stripped of all their subsaharan territories and forced to release Ireland, which I hoped would keep them busy. Sinking their almost equal and growing navy definitely played a hand in this too
After a sustained period of colonialism and taking chunks of France my income is approximately 1500/month and I'm making my way into India .. which I probably should be taking before Holy War casus belli expires
