" Xbox Live Arcade games have been following an unpopular trend lately. Microsoft has been bumping up the prices of many of the latest XBLA game available for download. The consumers who actually purchase the games are just as responsible for this increasing trend as Microsoft.
I remember the days when XBLA games were pretty much 800 MS points or less. However, games like Braid and Castle Crashers have paved the way for the 1200 MS point class. New games continue the trend with bit sized games like Load Runner going for 1200 MS points."
