So imagine a RPG coap game but at the start of the game you get to pick what country you originate from, and each country gives you buffs, so if your American you can get 2X gun damage and extra healing from American food and in China you start off with a wooden katana and as you progress through the game your katana will upgrade overtime, and you also learn martial arts as your main skill the whole plot around the game is a world war situation where every country is going at it trying to settle and overtime you make friends and alleys from other areas around the globe

Anyone can take this idea and use it, just credit me if you are using it
