Which is much better than their original plan of combining ALL PROJECTILE/LASER FIRING WEAPONS to just "Firearms."
Hehe, I can already see the controversy when they were planning this on Van Buren, though I kind of see it in the Dev side as players do tend to usually tag both Small Guns and Energy Gun many time in Fallout 1 and Fallout 2 while Big Gun is usually left in the dust.
Though it did use the overall idea of Deception Skill in the form of disguises.
I'd go the other way. I'd say there are enough contradictions with VB for it to be no more canon than the leaked early design documents of FO1. Some of the ideas are there, but there's significant changes.
Where my mutated raccoons? :swear:
But ya, so much ideas were uses in Van Buren to New Vegas that Van Buren is pretty much a stock pile of resource/idea rather than part of the storyline branch. I would not be surprise if the Dev would go back and uses some of the other ideas not use yet use in Van Buren but later use it in the later installment, like a crazy scientist who wanna rule the whole world or the concept of Vault 29.
