Games for Nerds Hall of Fame

I'm a sucker for lines, angles, science, simplicity and especially data.  So, I'm always on the lookout for great games that bring out my inner nerd.  Here is my Hall of Fame that I will update as necessary.  Let me know if you have a nomination.

1.  Quantum - All-time best nerd game.  Ultimate in simplicity.  CP only has a trackball on it.  You encircle atomic particles with lines you draw using the trackball.  The trail burns up as you draw so you have to do it quickly.  Run into one of the particles and you die.  Difficulty increases nicely.

2.  Qix - Draw lines with a button (fast or slow draw) and a joystick.  Complete rectangles to eat up real estate while crap tries to touch (and kill) you.  Major nerdcade factor.  Many clones over the years.

3.  Phozon - Use a joystick to build a molecule to match the goal of the pictured molecule.  Read my GOTD entry here.
