Anyone like to travel?
If you do, you're in for a big surprise. Most games allow you to traverse a made area. GTA 6 is rumored to let you traverse the entire United States. Life: The Game will let you traverse the entire planet, and space! If you plan on going across the entire world, you're going to need more than your feet....or in this case, more than a car/truck as well. There are scheduled airports in game that you can go to that will deliver you to your desired destination. Or, if you're feeling macho, "borrow" a military jet. Maybe they'll let you in if you say please. The way you'll have to travel will be slightly awkward for a while. Here is the way you'll have to move across Earth in order to get from country to country:
So if you want to go from Antarctica to North America, you can't fly South to get there in a shorter time. You'll have to travel North for the time being. The reason being is because the entire world is flat in the game but will end up having the realistic spherical shape of the Earth that everyone knows.
