Ms. Pac Man. My uncle was big into video games in the 80s (having designed and programmed Kaboom! for the Atari 2600) and he had a bunch of arcade cabinets in his garage. One of which was Ms. Pacman, which I still love.
I played the crap out of that game whenever I visited, and I got really good at the arcade version. So much so that nobody wants to play with me since I'll be there for 10 minutes or more on my first life. Once I was playing in Vegas and had a crowd watching me, it was really funny.
Nowadays, I will play it at the car wash near my house, and by the time all my lives are up, my car has been washed
The other game though that I loved in the arcade was the original Star Wars game. You know, where it was all monochrome graphics and stick figures. That's still one of my faves... it used to be in the arcade at Disneyland, but now I think it may be in Whitewater Snacks in the Grand Cal.
