During an interview for PCGameN, Scott Everts, the game lead world builder said that Fallout: New Vegas could've been better if it was a PC-only title and the game suffered from the console development, with features and ideas stripped from the game.
Fallout: New Vegas would have been a lot different if it was PC only. We had a lot of plans early on. Like, ‘Here's where the water is stored, here's where the farms are, here's where the government is centralised'. We had it all planned out - it wasn't just a bunch of random stuff."
We could have gone further with that. We had to simplify, so we had less stuff that would bog down the game engine. We would have had fewer performance issues. We did break it up a bit, but from my point of view it was a performance-related game and we had to fix things.
