I played that one a couple of weeks ago, actually. It's like a home-console Digimon tamagotchi, right? And you get stuck with Agumon? It... was kinda interesting, but didn't really hold my interest.
Oh yeah, if you ever DID like the Digimon Tamas, there's actually one you can download on the PC, and BOY does it have a lot of Digimon obtainable.
Japan only? Well, that just shot it! Unless it's translated, I can't play it. *Mutters something about not being able to read Japanese*
