In real life you can do much the same. The problem is we don’t see obstacles and enemies as easily as we see in the game. So the most important thing is to identify the obstacles so that you can mobilize and stack your resources against them.
Without a goal there is no obstacle. Even the jail wall is not an obstacle unless there is someone inside the wall whose goal is to get out. We are not clear about our obstacles because we are not clear about our goals.
Most people, when they face an obstacle they change the goal. This is the worst way to remove an obstacle.
