Soccer (NES / Famicom)

I remember looking at some of those early NES games where the art on the cartridge was just some pixels from the game itself.  Very simple, and it came far before pixel art ever became popular.  It was pretty neat, and Soccer was one of those simple games.  And boy was it simple.  Looking at it now, players moved painfully slow, it was a miracle to pass or shoot the ball, and actually scoring took some serious work.

Adventures of Lolo (NES / Famicom)

The Lolo series are probably some of the most charming puzzle games that I've ever played.  You play as a spherical dragon dude trying to save his girlfriend by unlocking one room after the next in a massive castle.  With a cute aesthetic, interesting puzzles, and a catchy theme song, it's hard not to like the Adventures of Lolo.  In a time where puzzle games are dominated by cold, sterile colors and shapes, it makes me wish there were more Lolo games today.

Super Spike V'Ball (NES / Famicom)

This game became quite the thing with my group of friends as a kid, though the huge push it was getting from Nintendo Power at the time may have helped with that. :p  It was quite a good game, though.  Very nice visuals for the time, responsive, simple controls, and it was actually pretty long.  Certainly one of the more popular NES sports games of its time that it would seem a lot of people today have forgotten about.
