NUCLEAR

In this (possibly true in the near future) scenario, In 2056, Stickman World (very similar to our world), Russia won against Ukraine. Then, a few years later in 2060, China attacks Taiwan, starting World War 3 on June 21st, 2060. Unfortunately for the world, the entirety of NATO was involved, and fighting against Russia, Iran, North Korea, China, Cuba, and Venezuela. And, what happened next? Well, China, Russia, and North Korea fired all of their nukes at the NATO countries, as well did NATO. It  destroyed all life on our planet. Are there survivors? Well, you are one of them. You are in Omaha, Nebraska, USA. The date is July 4th, 2077. It is finally habitable on earth again. Now, your goal is to restore life on earth. Oh, and did I mention that you had magical powers?
