Cause everybody loves Yu-gi-oh and it revolutionized card games All over, and people in the west haven't played a tag force game in years and all the games they made recently in the U. S doesn't feel the same as the tag force series did. All fans miss how you could meet your favorite character and be friends with him\her and you could help each other to save the world while getting to know the character more as if they were real and dueling with us. Also a 3ds release since they took out a lot of content in World Duel Carnival such as tag duel which alot of fans were most likely waiting for and since it would help increase the sales of the game.
