There were three arcades in the mall near where I lived in the '80s, a proper arcade, a bunch of cabs next door at the movie theater, and a few more cabs next to the Montgomery Ward's entrance. Now that mall is the headquarters of an internet hosting company.
I was in college in the early '80s, and could play Gravitar for like half an hour on a quarter, and two-fisted Gauntlet, pumping dozens of quarters into one character to get a high score on another character that had a single quarter. (high scores were divided by number of quarters inserted)
I remember being really unhappy about Pole Position when it showed up, in that you could only go four or five laps per credit no matter how well you played.
In my limited experience, you need a LOT of pixels for a vector emulation to look good on an LCD display. One of my all-time favorites is Gravitar, and the lines are just a bit too faint with a 1080 display, unless you crank things up. (specifically on my 17" MacBookPro, but I haven't tried it with recent emulators)
I think vector games might look pretty good on a 4K monitor, especially one with retina resolution. And then you won't have to worry about the vector driver hardware flaking out and spewing lines randomly all over the screen, something I've seen too many Star Wars cabs do.
