Yeah but New Vegas is far better than Fallout 3 in terms of being a Fallout game. Fallout 3 and Skyrim sold really well and got awards (at least Fallout 3 got awards so far) but New Vegas also sold really well. Out selling Fallout 3 within the first couple months of release and has won awards of its own. So Bethesda could take a hint and learn from New Vegas and the orginals and try to make a Fallout game with Fallout 4 instead of another TES clone that is Fallout 3. Not bashing the TES series, but Fallout is a very different series and should always be a different series.
I agree with Smert that Bethesda has it in them to make a awesome Fallout game that will satisfy most if not all the critics of Fallout 3. I hope the Fallout 3 apologists don't succeed in fueling Beth's laziness when making Fallout 4.
The problem is also the fans though. And I don't mean apologists.
What is Bethesda's ultimate goal? To make money. This is the ultimate goal of every company, and there is no company that says "let's aim for 300mil profit;" no, the sky is the limit.
And what sells? Sure, maybe New Vegas sells better to Fallout fans, but what are Fallout fans? A vocal minority. Gamers, as a whole, seem to enjoy something else. You can find plenty of let's plays on youtube with players who groan at the thought of having to engage in dialog with House, Caesar or Ulysses. You can find plenty of people who seem to thrill at the chance to shoot a gun, but can't be bothered to check the damn gun's actual stats and realize it's not the best for them. Like it or not, the common denominator of gamers as a whole seems to be this group, and their voice may take over.
You gotta realize that, Bethesda taking control of the series.... This is basically as if the Fallout fans are natives of Hawaii, and Bethesda is the US storming in to claim Hawaii as their own, deciding there should be a bunch of new rules. "You can't," cry the natives, "this is our home!" Bethesda thinks on it and says "you're right, let's put it to a vote," and the people vote on how things should be.
The problem is that ALL people get to vote; the natives of Hawaii and the Americans back home on the mainland, so even though it's the native's home, they've now become a voal minority.
And that's something Fallout fans may need to accept. Look at Skyrim. I don't mean to be overly cynical, but would I call Skyrim "selling-out?" Yes I would. Elder Scrolls used to mean "immersive" to me, but Skyrim feels more like "instant-gratification." There's practically no dialog or detail anywhere. We've actually gone backwards 4 generations when it comes to NPC dialog (yes, I'm saying Morrowind, Oblivion, FO3 and FONV all have superior NPC dialog and realism to Skyrim) What's happened with Skyrim, it can happen again with FO4.
We'll see though, time will tell. If things end up for the worst, at least we'll always have Vegas...
