Shigeru Miyamoto named SMW the game he was most proud of. I can see why that is.
SMW, Super Mario Kart and The Legend Of Zelda on the SNES are milestones of the genre, never again has this level of perfection been reached in 2D gaming imho (excluding SMK here).
The Legend of Zelda: A Link to the Past is no. 1 on some all-time best of lists. Maybe its the impression it made on many of us in our youth, but a year ago I played it again, and it was still great. The music, the art style, the controls - its the stuff that nostalgia is made of.
