One problem is that you couldn't sell the tribal pack. I mean honestly it is just complete crap I think my characters have thrown away all the items they are pretty useless. The armor looks stupid. The bleak venom is pointless. The broad machete looks gross and there are much better melee weapons in the game. The only thing of any use is throwing spears and those are readily available. If I were to buy one it would need to be cheap because I feel that the others were so much better so I feel cheated. And to note I didn't take in the pre order packs when I bought the game just purely the convenience of Amazon to me as at the time there was no gamestop where I live and I hate Walmart don't even remember the other vendor.
The point of those packs is to start you off. Most of it is to collect, I don't even wear my Vault 13 jumpsuit, it's for show. You shouldn't feel cheated for something you got for free. You pre-ordered, you didn't pay extra for it. Perhaps compared to the normal sales, but that's the price for ensuring a place for getting FNV.
