Great work on the Natsume NES action games article. Those are some gems most people should be aware of. Speaking of Natsume, you should consider playing (and if you've got time, reviewing) the KiKi KaiKai series of games (also known as Pocky and Rocky). I really like their gameplay and their numerous references to the Japanese culture and mythology, a-la Goemon.
Indeed, more people need to play Shatterhand. And see the US cover art, haha.
People really gave the NES the shaft as soon as the SNES hype hit hard. There are a bunch of great games that came out around 1991 or so that have been all but lost to time. Wurm is another title from that period I wish got more attention, but admittedly, it's not half as good as Shatterhand.
