Necessary for wii with game cube games

I bought a wii. It said it was compatible with game cube games. They were cheap. So I bought them. Then I had to buy the game cube controllers. Then, I had to buy memory cards. Belatedly, I realized that this memory card was the best deal, because the memory size is sixteen times the memory, while the price only double the standard memory card size. I'd be a lot happier if I'd known this to start with. So, i'm telling those people like me who buy video games for kids and don't know much about them. Buy this memory card, not the standard sized ones, and save money.
