Wow, I can't believe so many of you guys actually LIKED "Dragon's Lair". It's really the game that ruined it all for arcading IMO. It wasn't a true video game at all. Just a movie. To this day, I can't play the RPG-style games on game systems because it irks me every time the controls lock up and you have to watch some stupid video clip furthering the story. Probably a side-effect of Dragons-Lair-loathing.
So, no one remembers "Tac-Scan", huh? Man, that was a cool game. It was like that moment in Galaga when you captured your own abducted ship & got to fire double-shots... except in Tac-Scan you started off with something like 7 ships connected together, and each one would get hit now & then, making you lose one more simultaneous shot. Starting off with 7, though, you could ravage the enemy ships for a while.
Zaxxon... that was the other one I forgot to mention before. I remember the graphics in that one really upped the ante at the time. Before then, Vanguard & Galaga style graphics were as good as it got. But suddenly there was this 3D-looking Zaxxon game that popped up. By today's standards, it's pixelated & retro, but then it was mega-cool.
