Well, Boston is in fact on the coast. I'm not sure why this is such a sticking point for some people. Do you want the map to just cut off where the land ends?
Yep, that's the shape of Boston.
It's inconvenient if you wanted to build a settlement in the middle of the ocean but there it is.
Hey, it's still about the same size as Skyrim, we'll be fine.
Maybe they thought the ocean would be gone and dried up.
This does open up for some underwater exploration especially with powered armour or a space suit modded to handle under water pressures and oxygen supply.
It's more like one third of the map is water, at most. And the Endurance 5 perk confers water breathing, plus, compare the in game coastline to that of RL Boston, there's obvious evidence of sea level rise that would have submerged parts of the city that were closer to the water, so I'm expecting plenty of underwater content.
In a sense, it's a meaningless question.
The land mass is of a https://dl.dropboxusercontent.com/u/87106516/fo4_app_map.png. that of the Boston coastline.
If the play area was bigger still, it would still have a bay.
Do people look at Cyrodiil and complain because 40% of the map are in other provinces such as Valenwood and Elsweyr...?
Just...what did you think it would be? Seriously, it's the pip-boy, did you think it would be showing you a map of anything else?
... I still don't see the problem. Do you not like water? Map size and water ratio have absolutely nothing to do with the volume of content.
Bethesda made a perk that grants you the ability to breathe underwater. That alone, shows there's something more to do with the water.
It all depends now if they've done something interesting with the water areas. I've seen marinas, so I'm guessing lots of under water tasks to perform, ship wrecks, disused subs, maybe even a Bioshock style like habitat of sorts. Hoping for a sunken town (due to a burst dam) scenario infested by mirelurks. We do have that aquaboy perk to play with after all.
Because of the aquaboy perk I'm convinced there's going to be a lot of underwater stuff.
Not following this logic. The playable world space has to be surrounded by something, whether that's mountains, a "turn back now" message, or water. It doesn't determine what content is within that playable area. You're saying that if the water were land instead, we'd have more content. I'm saying that we would have the same content regardless, only within a different area. They didn't cut any content in order to put in the water. They decided what content to put in the game and put that in the appropriate place on the map. Unless you're equating raw square mileage with content, in which case we'll have to agree to disagree.
