I see Crusader Kings II on sale on Amazon for about $10.00 but it's $40.00 on Steam. A few others are cheaper on Amazon as well (e.g. M&B, Arma 2). Weird, but then I really don't understand the business relationship the two have.
Amazon and the big game publishers want to take steam's slice of the pie and eat it all themselves? Or if you mean Amazon cutting sweet deals with the publishers that would be an interesting question, but I guess it's just their perceived mass and the extent of their customer base.
Though since Amazon games are still US only I think it would be a terrible thing if they came out dominant.

If you look at the system requirements on the Amazon download, you'll see that Crusader Kings requires Steam to activate anyway. What will happen is you'll get a Steam code and you can just download it through Steam if you want. I did that with Deus Ex at Xmas.
Amazon doesn't really have a business relationship with Steam. The developer does. Amazon has a deal with the publisher that lets them discount the game occasionally, just like Steam.
That makes more sense. If I had known I would have made a thread earlier so everyone knew. Amazon had a Paradox collection sale (sword of the stars and about 5 other games) for around $30.00 and now it's up to $135. CKII is now $40.00 :(
