That’s a major part in the Ender’s Game series. They have faster than light communication, but the ships travel at like 90% the speed of light. So when traveling between planets, it’s like a two week trip to the people traveling, but 20 years on planet.
The main character Ender travels often, so he is only 35 in the second book, a couple thousand years after the first book.
Sony hasn’t done the paperwork to officially do business in those countries, so you can’t make a psn account. And because Sony is intent on forcing psn accounts, it leads to this stupid situation where those countries are locked out, despite Steam supporting them.
