Do you guys think that Fallout 3 would have been, project van buren had interesting things that should be given attention in the future?

I personally think it's a terrible waste they haven't utilized it more in the past.It had some pretty amazing lore and content, The Nursery, Boulder and Tibbets prison in particular got me pretty interested as very full of potential.

I was sad that they dropped mostly everything from VB and it didn't make it's way into F:NV.

No. It wouldn't make sense to have content that would have been in Van Buren at this stage. It wouldn't make sense now. Which is why New Vegas didn't just make what Van Buren was going to be.

Why not? They just have to take up what was started and...finish it.There is no reason why it couldn't work.
