So this is moderately interesting: Joystiq noticed that Amazon have come crashing into the casual games sphere with a
new repurposed portal that allows you to try-before-you-buy with around 600 games. There’s a time limited trial for each one, and they’re weighing in at around $7-10. Some notable names in there too: Kudos, Kivi’s Underworld, Jewel Quest, er… Chicken Invaders 3? (Two was clearly the classic iteration.) Anyway, there’s some free games on there this week, which always seems to go down well.
