i'm not a fan of nes games, but this game is amazing, especially the idea of hardware pushing wi-fi feature.
i'm more of a sega fan, though. if this game was on the 16-bit sega genesis/mega drive, it would look way better than the nes original, with several new features, more colorful graphics, larger and detailed sprites, and better sound quality. the wi-fi feature on the mega drive version would be cool, too.
