The second game will release on the Wii, and Marvelous plans on taking full advantage of the controller, allowing you to tilt the controller to water plants, pick up vegetables, etc. This game also takes place on an island, and it's been hinted at that the two may have some sort of connectivity.
Stay tuned to PGC as more info on these games are released.
Thanks to Jonnyram at the GAF for the heads up!
