My Boy Game Addiction

My little son is a game addict. I just bought him and his sisters a wii with four games last month and this Christmas he requested a Nintendo ds game which he had and another game for his sister. Just this morning he want to play his PlayStation and he said to me how about if I will get him a PS3 because it is better than PlayStation2. He is a bit spoiled and it is my fault. But this time his request will not be granted.
