This is my favorite game for the DS so far. I could also easily say Mario Kart but I won't because we all know that game is the sweetness. Yoshi T&G on the other hand, was a highly under appreciated gem.
IMO, this game was like Crazy Taxi in the sense that it was repetitive, and it had limited level sizes, but it was so damn addictive and fun that it kept me intrigued for a long time. The gameplay is just so tight and well executed that I can't help but keep playing in an attempt at beating my high scores. Absolutely delightful little game that was so underrated it's not even funny. I'm still bitter about it to this day that very few people seemed to *get* this game, and thus a sequel is probably unlikely.
