I don't know this community so I will introduce myself. My name is Chris Belmonte, and I have a strong interesting in Filipino history. I have family history with Filipino friends (I'm not Filipino myself). Anyway, There is a new computer game available called "Hearts of Iron IV."
Pretty much any nation can be played as. It's a grand strategy game. I plan on making my own mod for the Philippines, but as it is, you can play as the Philippines starting in either 1936 or 1939. This game involves economics (to a limited extent), building factories, manufacturing arms, technological advances, and of course, warfare on a grand scale. They update the game with expansions 2-3 times per year. It can be a bit expensive but thankfully heavy discounts happen from time to time.
