One of my favorites is Galaga. I play it whenever I see it. For those of you whom may not remember, it is a space invaders type shooter where they can come down and capture one of your ships, then if you shoot that guy you get it back in the form of a double ship. Also two vector-based games, Star Trek of course and Space Duel. The last one is an Asteroids type shooter with geometric objects instead of asteroids and two ships tethered together that two players could play together. For those of you jonesing for those old arcade games, I suggest you look into MAME, a game emulator that allows you to play all those old arcade games. Awhile ago, I was able to play Pac-Man, BattleZone, SpaceDuel, Joust, Spyhunter, Gauntlet, Galaga, AeroFighters, Star Trek, Star Wars (the vector version), on and on for nothing. If you do a search for MAME, I recommend the Germany site (ends in .de). That has the most up-to-date MAME versions and alot of ROMs (the game programs). It's also available on GameSpy under classicgaming.com I think.
