Very cool mod. Looks like fun. Noticing some stuff worth polishing though-
There's a lot of stuff in the races copied over from the originals that doesn't fit. Ghouls have the same personality modifiers as elves, so they're foppish layabouts. Vault dwellers live for 150 years and can be liked for their beards. Likewise, they both copy the entity settings, so ghouls name their sites after happy plants, and vault dwellers are ruled by kings and cover their artwork in spikes. And ghouls and mutants can show up wearing thongs...
On that note, a bunch of the DF flavor creatures, like marmots and the different birds, feel out of place, and could be exchanged for more post-apocalyptic stand-ins. Ditto for incidental stuff like crafts and toys. That's all just icing though. But definitely add in Horned Kangaroos. I can't remember if you ever even see living ones, but I can feel their absence.
As for the new stuff, it mostly looks great. The one thing I would argue against is making mutants size 12. Minotaurs, sasquatches, and horses are size 9, which seems more appropriate. But hey, 12 is cool too. Maybe I didn't play F2 enough, but is that where the wakazashis came from?
God damn that's a lot of guns. I took one look at the ammo file and went, "I'm never going to keep track of all this." Which means you matched Fallout perfectly! (As long as the subject is up, I'd like to mention that while the Pancor Jackhammer is a cool idea, only about 20 were ever made. Just for interest.)
