Monster Rancher DS hands-on at IGN.

"And so the Monster Rancher series lives on - the Nintendo DS is its new home, and TGS 2007 saw a solid build of the game on display for all to see. For those of you who are new to the series, Monster Hunter takes its roots from the Pokemon-style monster collection / battle gameplay foundation. With the DS incarnation, the emphasis is on using the unique input methods to try and summon a new creature every time you play, until you've raised them all."
