Amazon.com now carries Xbox Live Arcade titles, which can be purchased with real money, not space bucks. At this point it looks like they are just carrying the Arcade games and not any DLC like Rock Band tracks or map packs, though I would not be surprised to see this in the future. When you buy a title, Amazon simply sends you the code to enter on Live to get your game. Personally, I think that this is a nice service, and is a lot better than having to do “Microsoft Math” to figure out how many points I need to buy to get a few games. Now I can just pay my $10 or $15 and be done with it. No leftover points loitering around my account. I am curious to see if the prices on Amazon are adjusted to reflect any “sales” that Microsoft runs from time to time on particular games.
