They made such a success with NSMB and it was a really fun game; they should make the same with Super Mario Bros. 2 & 3. It would be cool to see 3-D Mario/Luigi/Peach/Toad plucking vegetables, or 3-D Raccoon, Hammer, Tanooki, and Frog Mario. Also, they could do this for SMW and YI (maybe not 'cause of YIDS).
I just hope the DS doesn't die out by the time Nintendo thinks about this.
