The official Japanese Xbox 360 blog has posted prices for Xbox Live's "Summer of Arcade" series (i.e. five weeks of awesome releases). Let's review:
July 30: Geometry Wars: Retro Evolved 2 (800 MS points / $10)
August 6: Braid (1200 MS points / $15)
August 13: Bionic Commando Rearmed (800 MS points / $10)
August 20: Galaga Legions (800 MS points / $10)
August 27: Castle Crashers (1800 MS points / $22.50)
At $22.50, Castle Crashers would hold the record for most expensive XBLA title. The total price for the Summer of arcade is $67.50, which is a little bit more than a standard Xbox 360 title + applicable tax. The prices are currently set for Japan only, but they generally don't differ with the North American releases. Is your wallet prepared?
