Unable to play as soon as received

Ok, so my kids were definitely excited when we received the Bakugan game. They were saying they had seen it on YouTube on Ninja Kids and they had also seen TV ads where kids battled. My husband and I on the other hand had never heard of it and were corrected by our children many times on the pronunciation. Excitedly, we opened up the game and assembled the Bakugan coliseum. It was very easy set up and good quality as well. Unfortunately, once set up and ready to play we found we only had one Bakugan and one set of character and ability cards. In order to play a real battle, we needed to buy more pieces. Once we have more pieces, I believe my kids would have a lot of fun playing this game. Playing instructions were hard to grasp as an adult, but the kids seemed to be telling us exactly how to play it without ever playing it before just based off of what they had seen. So all that excitement for nothing....until I get to the store.
