Yeah, Mario's Picross saved me from bordom many a time. Good old GameBoy version =)
IMO, this puzzle collection is a terrible rip-off.
To my knowledge it only features two games, am I right?
I'd like to see a real collection featuring Dr. Mario, Tetris Attack, Tetris: Bombliss, Yoshi's Cookie, Wario Woods, Kirby's Ghost Trap and ... Well, everything!
