King Arthur Collection does not include King Arthur 2 right? Because the one in Steam includes KA2 and it's DLC as well.
It does not, that is why KA2 is listed in the package. And it is just the base game, no DLC. In fact, when I goto the KA collection in my library, and goto "store page" it doesn't find anything, and reverts to the store home page. I think the Amazon keys are from the old "collection" before KA2 came out.
