As I'm sure we remember, when Xbox Live switched over from Microsoft Points to proper money, they gave everyone a bit of free credit (either that or I had a lot more Microsoft Points than I thought I did). I've been wondering for a while what to spend it on, then I found out that Crimson Skies: High Road to Revenge is available. Needless to say, I'll soon find out if it's anywhere near as good as I remember it being.
Oh, I'd just like to mention that in that game, your planes are kept on a giant tie rack inside your personal zeppelin. That should say all that needs to be said, really.
