Played the game as Asia with 5 human opponents.

I started my game with allying two alliances(RU-NA, who I knew were at least average players and AF-SA, who I knew were very new as they placed in 6-fleets, but I guided them through game about diplo mechanics and even friended them both afterwards).
Then I made a deal with AF for placing 2BS and 2CV at Indian, athough he only placed 2CV(I also placed half of my subs there, some for "Indian Armpits" and some for being placed under AF).
After that I placed my main fleet to Japan and a pair of CVs and BS along with the rest of my subs to mid Pacific to middle of the naval deployment zones(this was for quick assistance for an American conflict if such was to happen).
Then I helped everyone destroy EU(meanwhile advised AF-SA to move their Atlantic fleets to North).
SA then moved fleets at Pacific to US coast, so US navy was still between them and the coast. No fire exchange happened yet, but NA warns publicly about SA so I move my small assistance fleet to encircle SA fleets and main fleet following soon.
As this happened Russia, who had originally prepared to face SA, pulled away once noticed I was on my way.
SA soon started fire on NA and AF-SA start to engage NA in the Atlantic.
I open fire with my entire Pacific fleet on NA, who is simultaneously kicked from the Green Alliance and conscutively wiped out.
Right after the NA fleet was destroyed I quickly open fire on SA fleets and wipe them out.
AF-SA started to question me, but as RU left Green Alliance and attacks me, we concentrated on him instead. RU was wiped out without much effort(note that he had to leave soon so he was just messing around and then left CPU to handle the mess).
After wiping RU, I used my submarines to nuke SA silos and cities.
SA then left Green Alliance and was joined by AF(we had a bit of conversation about loyalty with AF first, but then he noticed I wiped out his CVs in the Indian Ocean and was starting to nuke his border radars).
Then I nuked AF silos and cities with submarines and use my bombers for complete destruction.
As victory timer started, I used my silos to nuke RU, which still had quite a lot population left.

Game over!
Victory goes to Asia with more than 70% of the population still alive.
