Travel is gonna become boring if you have to travel the same road multiple times in the course of the game even if you have a bunch of cool stuff along that road. Eventually, I won’t give a shit about that stuff since I’ve seen it a million times. So I would hope there is still some kind of fast travel to go between places I have already been if the world is super big. Otherwise it’s just gonna feel like you’re padding the game for time to inflate a 10 hour story to take 40 hours to finish.
