So ... what exactly were you against in your previous post then? O_o
I wasn't "against" anything. I was asking for bigger and more complex dungeons...Things that we'd like to have in the final game? I'm sorry, but are you even reading the thread?
If anything the real question should be: what are you even ATTEMPTING to nitpick about?
But tell me, how far they are from the beach, where we are told we are in "middle of nowhere"?
No matter if you use Kilometers, or Miles.

(
Hint: We do not know. :P )
"Not very" is the correct answer, regardless.
You can march your way from the beach to the goblin camp to the Underdark entry and then to the subterranean lake in five minutes TOP (if we are choosing to go through the most orthodox path and not the faster alternate ones) and even by putting some abstraction into the equation I don't think we are sailing on that boat for more than few hours top (but let's be real, it's probably a lot less).
