Yeah, that is very true. This is a very large world, and I don't think a few weeks will cut it, especially since I'll probably only play for an hour or so a day, if that. We will see!
Anyway, is that 150+ hours of gameplay your guess, or is that the opinion of the actual gameplay?
not a guess, but a fact, just serched about it, at first i just read it on some forum but now it is real, just search like how many hours of gameplay there are. there are a bunch of websites saying it has been confirmed there are at LEAST 150 hours of gampelay
