What is this game called? Not Itadaki Street DS, not Hotel Mario, not Yoshi's Saari, not Super Mario Bros. the Lost Levels and definatly not Tetris DS (it's...not a Mario game is it?) The name of this game?
Yakuman DS.
Yes, Yakuman DS.
No, thats not Mario playing Poker. Here's the character select screen:
Goomba's playable...and Bowser Jr. is playable...very surprising. Shy Guy, Koopa and Boo are also playable. But uh, anyway.
This game is a Japan-only game, released in March of 2005. And this game doesn't look fun at all. I mean the game is about Yakuman a Chinese game. Chinese game...in Japan...hee.
We have something to be thankful for this Thanksgiving: This game was Japan-only and wasn't released in America.
