Yugioh has got to be the worst excuse for a game and a show ever since the beginning of time... I used to play it when i was a kid, But now it just sucks very badly... I realized that when i grew up.
Try 21 (Or Blackjack, as it's called in some places) or poker. Much more interesting and not so complicated. And you can gain a few cents if you do minute gambling, although that's not recommended for beginners.
I used to collect them, but then I sold my deck of like 1000 cards for like $5. . . .
I used to collect them as well when I was about 10. I planned on selling them for at least $25, but my brother stole them and my mom made me let him keep them. Now half of them are ripped up and the other half are scattered around the house. Oh well.
