There are things I wouldn't mind saying to you right now, but I'm pretty sure they'd get me banned.
Suffice is to say, no, Fallout 3 and New Vegas are not turn-based in any way whatsoever, and you are completely incorrect for thinking so. The difficulty in bringing up your Pip-Boy is due to animation delay - before putting the stupid gadget up to your face and hitting the "pause time" button, the game waits for any animations your character is performing (usually reloading) before bringing up the menu. This a natural consequence of Bethesda's asinine "let's put cool [censored] in our game without a single thought as to how it would impact gameplay, lore, or narrative" approach to design, an obvious example forcing something that should be easily accessible and functional (a menu) to be of secondary priority to their AWESOME NUKE CATAPULT RELOAD ANIMATION BRO.
What you're doing is effectively looking at what is best a terrible design decision and at worst a bug, and calling it a feature in order to contort into some completely arbitrary and incorrect misconception of what turn-based gameplay is. Which I guess is par for the course. You should give Todd Howard a call, they could use more people like you at Bethesda.

Nerdrage much, my friend? Wow. Methinks you need to step back, take a deep breath, and get a life. I think there are far more important issues in the world worth getting upset over than my mere trifle of a post. But what do *I* know?
But, either way, you're incorrect -- look up some of the development history of not only the post-Interplay
Fallout series, but also
The Elder Scrolls, going back to at least
Morrowind. The Gamebryo engine utilizes turn-based gameplay and combat, but it's under the hood, and damn near invisible, except at certain moments. The "dice-rolls" occur offscreen, in other words, and so rapidly that it appears to be "real-time."
You need to conduct a little basic research first and get all your facts straight before coming in here and acting on impulse, amigo.
Bad voice acting? What little there was in the originals was actually better than in either of the new games, and quite good on general level.
But you're right, nostalgia is overrated. Good thing there's hardly any at play here.

Voice-acting-wise, the originals were strictly hit-and-miss, at best. Richard Dean Anderson, for instance, sounds like he was rolling four Valium deep the day he showed up at the recording studio.
