In my opinion, although E.T. on the Atari was voted the worst game ever, my least favorite NES game back when 8-bit was king was Clu Clu Land. Something about it just made me want to do anything except play games. Hands down, my favorite game of all time is the original Zelda. I've played it to death on every Nintendo it's been available on, as well as emulators, but there is still something about the originality, puzzles, overworld, dungeons, and the variety of weapons and tools that make it my favorite.
