Perhaps you have missed them, but there have been threads about the perceived lack of 'epic' in New Vegas. The opinion on most of those threads was, indeed, that while New Vegas was less flashy than F3, there was much in Vegas that could be considered 'epic'.
I believe it's safe to say the exploration issue is a separate one.
I agree that there is much distillation of opinion and I question the science. Maybe we need to establish a point of reference? I know nothing about Fallout fandom except these boards. If you ever hear me say 'fandom', this is what I am referring to. What about the rest of you? When you refer to a body of fandom opinion, what's your source?
Edit: Eh, Styles beat me to it.
Yeah, you're both right, it was likely a poor choice of words. But I guess on the bright side I just demonstrated one of the effects of this split. It's easy for me to become hostile like I just did because the possibility of it being a poor choice of words never entered my mind, instead I assumed it's just someone trying to insult all of the Fallout 3 fans with legitimate reasons for not liking New Vegas.
I have not seen "New Vegas isn't as epic" threads anywhere, and because of this all I'm aware of in terms of why people don't like it is what I already mentioned; exploration and atmosphere. So, in that case, I apologize. But I would appreciate if, in the future, you didn't make it sound like the only reason FO3 fans didn't like it was because it wasn't as epic. That may be a reason, but it's far from being the only reason.
I'm glad this misunderstanding happened though, not only did it demonstrate how easily arguing and misunderstanding of opinions can arise when discussing Fallout, but it's also made me think about how I react when I read (seemingly) biased posts.
