They have to chose, massive open world, or focused immersive story.
Pretty much. I don't really go into sandbox/exploration games expecting a great story - I go into them expecting a great sandbox.
Which is why....
New Vegas had both. Granted, the world wasn't as big as Skyrim's (or at least I don't think it is) and the game is much, much less focused on dungeon crawling, but still.
...New Vegas disappointed me, and I prefer FO3 to it. Because I went into it (since it was made using the FO3 engine & assets) expecting a similar exploration game. And instead got a generally linear story-based game with a somewhat boring worldspace. And yeah - that's at least partially my fault, for expecting a Beth-style sandbox. Doesn't change the fact that I haven't felt the desire to play FO:NV again, while I keep loading FO3 (and Oblivion) back up.
(and it's not even an issue of not liking linear/story games - I love JRPGs and Bioware games, for instance. It's mostly a case of going into it expecting a different game. And because my expectations were so different from what I got, it's colored my perceptions of the game ever since. Probably not fair, but that's life. Ah, the mysteries and silliness of the human mind.

But anyway - that's why Skyrim didn't disappoint me (not really). Because it is basically what I expected it to be. I didn't expect it to be a Bioware game, or even an Obsidian game. I expected it to be a Bethesda game, and I got exactly that.
