Title. To understand how the world works for a dumb man like me forza eliminator was the key. This post is useless if you don't know what that is. But this game mode answers the question why the wars will always remain on earth, despite how evolved our civilization will be. You know, to win in forza eliminator, the only thing you need is to win the final race. You don't need to eliminate others. But you do eliminate others in order to get a better car, have higher chances to win the final race and also not get eliminated by another car. That's just a vicious circle. It's like eliminating others is not exactly what leads you to the win. But you still do that to survive because you CAN do it.
That game gives you the answer to a question: What is more efficient - a good army or a good diplomacy. I think the answer is clear
