From what we know about Fallout NV are there features in here that you wish were in Fallout 3? As I stated in another post, I would have enjoyed being able to decide which faction to help. It was a little dull being locked into helping the BOS.

Fisto.

Everything? is that bad?

Going for the "Simple things in Life" approach?

Nothing. I'm glad we'll be seeing a ton of great new features in New Vegas.

I'm looking forward to trying the companion wheel - if it works how I think it will, I think that's the thing I'll miss in FO3.

I like the Reputation system.

But I wonder how FO3 will be from now on.
I mean, once we get a taste of Vegas' reputation system, companion wheel, hardcoe mode, setting, characters, balance, extensive weapon/crafting lists and Fisto I think it will be very "meh" to go back to FO3.
Might even be unplayable because one has changes it's standard.

hardcoe mode.

hardcoe mode.

Street Lights, Tuxedos, Matthew Perry.

If we had everything in Fallout 3, Fallout New Vegas would look like an overpriced expansion pack instead of a standalone game.
