Why are you "required" to get any of them? They're bonuses - like getting a promotional glass for a movie at McDonalds. (plus, they're just items with slightly different textures or stats, or gained earlier - it's not like additional quests or zones.)
Why did I run around the capital wasteland collecting skill books or unique weapons?
Because I wanted to complete a collection of those items.
So with this I cannot complete the Vegas collection.
And I'm not required to buy them but it will always be picking me in the back of my head that I will never be able to complete the collection.
That's what pisses me off.
And I know "what's the point of the collection?".
Nothing, just as pointless as pressing the LS button and placing items in your megaton house to decorate it, yet alot of us still do it.
And I'm not against "a" exlcusive but four different one's is what's irritating me.
It means basically noone but the one's with too much cash on their hands will be able to get all of these items.
