I just don't like the way people keep saying that, that it feels to them like it didn't have 4+ years of development time. Cause when I roll through it I can see why it took them 4+ years to develop the game.
The Witcher 3?
I think part of the problem is that Beth has been making this kind of schlock for the last 15 years or so. You really can't consider them amateurs by any standard. And yet, a company like CD red, with less funds, less people, less experience, blows them out of the water with almost all of their games. I mean no mater if you take TW1, 2 or 3, each of those games is better in beeing an RPG than any of the Bethesda titles. What ever if TW3 is the perfect open-world-RPG, is a whole different story. But compared to F4 it deserves the title goty.
So naturally you simply have to ask your self, 4 years (probably more) for this? Exploration aside, is it really THAT much? Is it more or less compared to Skyrim? I would assume that Fallout 4 contains at least as much copy-pasta-content for the player to devour like Skyrim, Fallout 3 and Oblivion. Add to that their shitty Radiant quest - probably one of the worst things ever. And you get what? 1 year of development for it? Again, they should have most of the tools, the people, knowledge etc. And yet. They still barely improved anything here from Morrowind, outside of the visuals. Hell, making Fallout 4 should have been even EASIER, if you consider how simplified the whole gameplay and system behind it is, no role plaiyng, less narration, less stuff to test/check, no skill based system. They have been pretty much in the same position like Obsidian here, and yet, look what they achieved in 18 months. If that is the best Bethesda can do in 4 years.
Besides, I have read that people from ID software actually lend a hand in the making of the gun-play. Who knows how much they did and to what extend that help was. But even here, some say that Fallout 4s shooter gameplay falls a bit short to what you get in most
pure shooters, where the RPG part isn't bolted on it for no reason.
*Edit
Well, we can all only speculate anyway, since no one of us works at Bethesda. But when I think about it, I can't help it but think, that they have this concept or idea with making games. Some approach where the goal is to sell as many copies to as many people you can, with the least amount of resources and money thrown in the project. Look at their marketing this time around. Not even their marketing and hype machine was as big like with Fallout 3 and Skyrim. Or at least that is the feeling I get from it. But I could be wrong.
