I am so fucking pumped. Is it just me who assumed that your character is neither the parent shown, or the baby, that's just a cool character creation screen, and then you play as their great-grandchild who happens to look just like their ancestor? Because I agree, anything else would be weird. Then again, in F2 your backstory was limited to a tribal with a family with set personalities, descended from the vault dweller, etc. and that was alright, and in New Vegas even where you're a well-travelled courier. So I'd say a loosely set backstory wouldn't be the end of the world, but I'm still hoping there isn't one.
Crafting's going to be so fucking great. I figured Fallout was all about the new civilisations that sprung up after the bombs wiped the slate clean, and how the people dealt with the remnants of the old world, and building your own settlements out of old world crap lying around sounds absolutely perfect. As for weapons, ever since the Jury-rigging perk I have hungered for more substantial repairs and modifications and this is a definite dream come true to be able to make your own instead of loitering outside the Gun Runner's shack until the part I want is for sale.
Voiced character, sure whatever, actions speak louder than words, it's not like Mass Effect was shit for having one. I'll miss the skill checks though.
Dog? Dog!
Bear in mind guys, Fallout is a peek at what 1950's America imagined of the future, and it's never been the most serious of games (side-eye at Fallout 3) so fuck yeah give me that jet pack shit I'll punch a BoS pilot in the dick mid-flight.
