It's quite the coincidence that after challenging our brains week after week about how the Xbox "Deal of the Week" is determined, Brain Challenge ends up becoming this week's offering. The glorified mobile app isn't "bad," but we still have to think real hard if it's worth the 400 ($5) price -- at its standard 800 ($10) price, we feel a purchase would put us in the same category as Abby Normal's cerebral matter.
If you're in the market for some cranial exercise, this would be the week to get the Brain Age clone. Just be prepared to learn that a purchase is unlikely to make you any smarter.
