you have fast travel, a helicopter, vehicles, a horse and a walker gear, and you can speed up snake himself. with any of these tools it only takes 2-3 tops to get from/to anywhere in the game. I played on PC so loading times were almost instant. Don't know if that was different on PS4It was spent traveling. Breh, if I'm in the middle of some outpost that doesn't have a fast travel location, I can't fast travel to somewhere else. Going back to ACC and reloading to a new spot was time consuming. Then again there are outposts where the fast travel thing is there but because of what's going around you, you end up missing it. Like the area where you first go to meet Emmerich. I missed that one because I was busy fending off Walkers and a enemy gunship. Next time I had to go back there I had to literally travel all the way out there. You end up getting more fast travel as you play but by the time you get them you're pretty much done with the game. That was my main gripe. The game gave me tools too late. Idk man, I just don't really like that loadout shyt. I rather just have mad weapons equipped.. Speaking of weapons.. what happened to that?? MGS1-4 you could have multiple weapons on you. In MGSV you're limited.
The story missions almost never made you travel far unless it was part of the mission, like sneaking through a couple outposts to get to the objective, or finding non-stationary targets
