I'm a fan of Cooking Mama on DS. I didn't like it on Wii at all. The controls barely ever work. I have no problem with the voice acting or anything else. Just the mechanics of the game and controls are really bad.
In some instances you are supposed to do something like breaking an egg. Well, the game is horribly designed so if you do the same motion twice once you will barely fracture the egg and the next time it will break completely and you'll fail.
The game really lacks in instructions too. It tells you to do something but leaves out a few steps. So you won't really know sometimes when you're supposed to press a button or turn a dial because it's not in the instructions.
The game could be great if the controls worked and there were clear instructions. It seems unfinished and hurried. I should also point out the DS version was 20 bucks and the Wii version is 50. Yet the DS version is way better.
