Taito announced Gardening Mama for the Nintendo DS. The game will release March 19, 2009 in Japan. Gardening Mama haves the same concept as Cooking Mama. It's the intention that you're going to plant patatoes, fruit and vegetables. You can find a few images below.
Hopefully this game will be decent. I got all excited when I saw the box art. . . I thought it was going to be another Cooking Mama. :/
Gardening just seems like it would make the pace of the game slower.
