Yes, underground dueling is a kind of play with no rules
if you mean online pc games theres kaiba corp, yugioh dueling network thats all i know
yes there is yugioh gx also there will be yugioh 5ds i really dont think 5ds will be very good because they are dueling on motorcycles but there might be an interesting new dueling mechanic to make duels more interesting. Guess we'll hae to wait till it comes out in the U.S.
no there are no rules in underground duels
You can return to the Facility after you have completed the Story Mode.
no only if the other person gives up
I would say yugioh..way easyer to learn..they have touraments..and Pokemon don't even have a rule book...i have 4 years of yugioh dueling experience
You draw 1 card, as usual.
There's DevPro (type in devpro yugioh), you can download it or: Dueling Network (no download, just sign up)
Completing downloadable Duel Puzzles, as well as dueling computer and players online, is another way to earn DP (Duel Points).
The physical transformation is for our benefit. Some other characters note that he looks like a different person while dueling.
Keep dueling him and giving him sandwiches to get closer to him and I think you will be able to buy it.
probably the very first episode where yugi/yami duels kaiba the first time or when he is dueling pegasus in the first episode near the end of it.
