A Awesome NDS game for Digimon Fans. Digimon World DS. It looks like it has every Digimon in all the series of Digimon in the game. Over 250 Digimon at least that is what I heard online about the game. I don't know exaclty how new the game is but check it out at the following site:

IGN: Digimon World DS

There is also a couple more digmon games for nintendo ds. But It looks like these ones are just story mode and not collecting all the digimon and making the evolve.

Digimon World Dusk
