One side note. Some of us (years ago) chastized the author/developer about putting rocket launchers on a spacecraft sent in peace for all mankind to another world.
He may have taken them out, but I have not played the game in years, so I don't know if he did or not.
There is a "checkbox" somewhere in the options menu to turn "rocket launchers" on or off.
o7....
IGN has a pretty excellent free online version of the regular Atari Lunar Lander if you don't like the rocket launchers. I went to a vintage arcade/bar place a couple of times recently that was really cool but I was irked they didn't have Lunar Lander as I've gotten my skills pretty sharp. They did have Star Wars: The Arcade Game, Star Trek: Strategic Operations Simulator and a bunch of other cool crap though. And some game called Lunar Rescue that was sort of a mix of Lunar Lander and Space Invaders... which admittedly sounds cool but I wasn't a big fan.
