[I never played real Yu-Gi-Oh cards myself, only video game versions of it. I loved what little of the manga I could get my hands on though (they stopped it here after 11 or so volumes). I thought it was excellent.]
I've never heard of Fruits Basket, but I like Naruto, so I'm going for Naruto. I looked up Fruits Basket now and it sounded interesting. Still going for Naruto though since it's the only one I've actually read.
Ranma 1/2 or Naruto?
