Best HOI ever, at least back then they did not nickel and dime you to death with predatory business practices and actually delivered whole game.

First proper playthrough I chose Saudi Arabia 1914, had no clue what I was doing, saw Mexico get split into two factions who control it and start expanding into America. Saw Germany fight two fronts against Austria-Hungary and Russia while smacking France about like Ike did to Tina Russia split into a multi faction battle royale and fight each other literally a week after Russia changed into Soviets I was lost, confused, watching all this go down while chilling as Saudi Arabia trying to figure the game out but damn it was a blast and I can't wait to learn to play
