Depth = Immersion
Skyrim will be to Oblivion what Oblivion is to Morrowind. Less depth, more mainstreaming, less good. What's worse is that we'll all buy it no matter how bad we think it'll be.
If anything it looks like Skyrim already has more depth than Oblivion.
I can understand other criticisms, but this is just dumb. If this tidbit of news alarms you, you have a serious problem. No elder scrolls game has had unique dialogue for generic NPCs.
No elder scrolls game. If it hasn't affected the genre in the past, it won't now.
I say keep their idea for having only specific people have important voice recordings, but instead of making every other NPC into a meaningless ornament, bring back Morrowind style text. That way, you get the depth in all characters, but you don't rack up insane voice acting costs. Are people really that put off by reading? They act like they have to shovel their driveway or something. I love text in an RPG, and still prefer Morrowind's text to Oblivion's cheesy and ridiculously awkward conversations.
I love Morrowinds text system, but when it comes down to it, it's really all or none when it comes to text. With the way Oblivion style NPC interaction works, having split text/voice wouldn't work. Old RPGs are partially "imagination based" wherin you have a bland generic face, and the game simply describes a lot of stuff to you, this is not so in the new games, they try to visualize it. You can't suddenly switch between voice and text.
BUT, Simply recording generic info options wouldn't be a lot of work. Basically the same system as morrowind with lore/info/news topics, but the responses are recorded for each race, gender, and voice actor so it's voiced rather than text. It really wouldn't require much work at all. (though it may take up at least 100-200mb of file space)
