Uh, NO, the gun animations looked EXACTLY the same, down to the T, the factionswere by no means MEANINGFUL, all the they did was have adifferent leader, with the same damned quests, all of them except the NCR said destroy the brother hood, and seriously, a follwer wheel? That would take a whole 5 minutes to develop. The game had hardly ANY Improvements from FO3, which was eons better than NV. Even the aim down the sight function was broken most of the time having your gun move up and down and being unable to fire. There were already recipes to create weapons in FO3, all they did in NV was add some.
How can they look exactly the same when:
-Fallout 3 had like two lever-action rifles, and the lever-action rifles in New Vegas don't have the same animations as those in FO3.
-Fallout 3 didn't have any guns that loaded one bullet at a time. Every revolver, rifle and shotgun that loads one bullet at a time? That's an original FO:NV creation.
-There's dozens of new guns. ALL the shotgun types are new, every revolver except the .44 magnum is new, the marksman carbine, the assault carbine, the service rifle, the 9mm, every DLC weapon (cept the Yao Guai and Deathclaw guantlets), all lever action rifles except MAYBE the La Lounge Carbine (I never use it so I forget if it's the same animation as the Lincoln repeater). And that's just guns. Explosives and melee have several new weapons too, with unarmed having several new animations.
How the [censored] were the factions not meaningful? Missions they offered, Caesar and NCR look quite different, as does Indy in general. The missions were somewhat similar, yes, but the dialog, rewards, the way people react to your decision, the reputation consequences, the path you take on those same missions etc. were all quite different.
I dunno how the hell you think the iron sights are broken.
And I dunno if you realize, but practically EVERY misc item in Fallout New Vegas has a use. In FO3 you want pre-war books, parts for the crafted weapons and scrap metal. Everything else? Forget it. In New Vegas? Basically you don't need the vacuum cleaner, the motorbike parts (two of them), that one part that was used in the railway rifle....and that's it. Everything else has a use. Yes, even the burned books.
Actually only about 3 years. Fallout 3 was released in 2008, Skyrim came out in 2011, which is why I think they should have spent a bit more time on Skyrim, three years doesn't seem like a long enough time to develop such a large and complex game.
The 5 years time is quoted from Bethesda themselves. Your statement is just speculation.They've confirmed otherwise.
