This was released earlier (different region or something I guess).
Anyway, it surprised me. It's much more interactive and 'realistic' than cooking mama. I'm still playing Test Kitchen mode to unlock more stuff.
There's also a mode where you can take whatever ingredients you've unlocked and start cooking whatever you want. It'll copy what you did and create a Cook Book style recipes for you!
For Example:
I buttered a pan for 40 seconds on high and put in three eggs. I put a cover on the pan and fast-forwarded 30 minutes.
Spinkle a dash of pepper and viola! Burnt eggs a la moi. (yes, you can name your recipe).
As an added bonus, there's a shopping list mode for recipes. So, if I took that recipe that I just made, it would list butter, eggs and pepper. You check them off (with the touch screen) as you purchase them.
...but the thought of walking around the grocery store with my DS is kinda' nerdy. Which is fine
