I meant that it was forced down your throat at every turn - every side area seemed to try to be relevant to the plot in some way, whether through content, story, or something else - it's unlike how in Fallout 3 and 4, most areas don't even reference the main plot, but have their own little interesting story or reason for existing. Not that those areas don't exist in Fallout NV, just that it feels like Obsidian did everything they could to make sure the player knew that Ceasar's Legion and the NCR existed and that they did things in places. It was as if almost nothing could exist outside of the main factions.
And I suppose you have a good point, but I've seen Deathclaws right around Hidden Valley, and though I've stealthed around the Deathclaws in the middle of the map myself, I think it's a totally stupid way to coerce a player into taking a certain path their first playthrough. My first time in Fallout 3, I didn't even realize there was Megaton until after I'd wandered far off, and ended up fighting an Ant Queen just for the sake of it - it felt a lot more organic, and in general was a lot more fun to do than be forced to go through a few of the same areas almost every time.
