The Nintendo DS game Tamagotch no Narikiri Challenge is a heart-stopping, at-first glance, intense battle for control of the device between two players of the Tamagotchy type. The game, originally announced for the Japan-exclusive PlayStation 2, comes to us courtesy of Nintendo's blog, hand-íg hot on the heels of the console itself. The game is set in a fantastical world of missed chances and final, sayable conclusions. The feel-good, ancillary value of this little known game is that it's free, which means that not only does it come with a built-in entertainment value, but it's also free to play on the internet. Tamagotch no Narikiri Challenge is a game that, in its own right, is worth playing, not just because it's amazing.
