I just got a Nintendo DS need some games

I know I am going to make you laugh, but I am going to ask you anyway. I want to know what is Nintendo DS. Is it a game player? If it is, if we want to play games do we have to buy the CD or what? I love playing Diner Dash and Cake Mania and until now I don't know they are selling these games in CD form. After reading your discussion I am very eager to find out whether there is a Nintendo DS in my country. Lol. Don't laugh, please. I play other games which is almost the same as the two. They are Delicious Deluxe and Delicious Deluxe 2, Nanny Mania and Burger Island. I think you will like these games too. All of them I play through the internet from the limited free version. I love to look around for Cooking Mama, I haven't heard of this game yet and hoping I might find it in the internet. Well, nice knowing you and do take care. Have a nice day and I hope your daughter is alright by the time I post this. It's been three months now. God bless.
