Oh, interesting.

I have this ultimate Edition thing, aren't these DLC already included.
Well It would somehow look cool if the warden's love interests has a "partner look" outfit but that is not going to happen.
Other than that I already should have most of the DLCs, right?

I don't think so. The Ultimate Edition didn't have the promo items.

So where are these from? Are they all from the Collector's Edition or are there some from other sources?

They should just give away the bigger DA2 DLC. Or are they really still making any money from them? Something tells me no.

Wow. I am currently playing DAO vanilla, so these should spice things up a bit! Classy move! Do more of this and we might forger all the horrible, horrible, horrible things BiowarEA has subjected us to!

Promo items were available at specific retailers. The only way to collect them all was to buy/pre-order the game multiple times. Or just get a "torrent ultimate edition".

I already own all the DLC for Dragon Age, I picked up the platinum edition last year on the Steam X-mas sale. A great deal for those without the added DLC. +1 for starting this thread.

I actively want to avoid having these overpowered promo items in my inventory.

Thanks for this!

How exactly do I get my xbox to "know" I have these?

Heh, I had the Collector's Edition of Dragon Age: Origins (on disc), then bought Ultimate Edition (for download) when I decided I wanted the add-ons (because it was cheaper than buying the packs separately, even if I cut down to not buy everything), so I had a bunch of the applicable ones already.

More stuff to sort though and throw away though, yay! If I decide to go though the game again, that is.
