The Simpsons game, Yie Ar Kung-Fu (Tonfun and Blues…how I hated you) and Pac-land.
Gyruss, the only game I was ever really good at. Great Bach theme music, too: Diddle-EE! Diddle-iddle-ee-DEE! Diddle-EE! Dee-dee-DEE! DEE-DEE-DEE-DEE-diddle-EE! {Deet-deet-deet-deet-deet-deet-deet-deet…}
And Elevator Action, because I still can’t get the music out of my head nearly 25 years later. Yer classic arcade has to have those tinny themes that still set the index fingers of an entire generation twitching in Pavlovian anticipation whenever they hear them.
Oh, and a laser disc video jukebox showing Cyndi Lauper and Pat Benatar.
I’m seconding Scramble, Defender and Berzerk (ah-ha humanoid, ah-ha intruder).
I’m adding that great tabletop x’s and o’s black and white football game, with the track balls (so you’re facing your opponent at opposite sides of the table). Great game, as you each are spinning that track ball for all it’s worth, chasing or running away from your opponent’s x or o. The great grand daddy of all that is Madden today.
•Silent Scope
•Vortek VR with Operation Blockade
•Aaaaand…either HydroThunder, or Toobin.
Oh, can I add one more, after all? Monster Rampage. Silly, pointless, and probably offensive.
But I loved feeding that game quarters.

Well nobody else so far has mentioned Mr Do! Which is a travesty, because it is a stone cold classic (if you don’t know it, it’s like Dig Dug but with bouncing balls, and it’s much better). One of a very few games that I still sometimes fire up MAME in order to play. The others being Galaga (glad to see so many votes for it) and 10-Yard Fight - a surprising choice for an Englishman perhaps, being an American Football game, but it had, for its time, immersive controls. You had to weave through the defence and waggle the joystick about to shake off tackles, and it really did make a difference how hard you waggled the thing.
I hope the arcade has room for the only video game that I ever truly dominated.
I could go for an hour on one quarter.
I always loved the Elvira Mistress of the Dark pinball machine myself.
As for the games:
Battletoads
Golden Axe
Sunset Riders (“Bury me with my moneyyyyyyy”)
Virtua Cop
720
Narc
Definately seconding the Iron Man Ivan Stuart game since spinning that wheel and cranking on the nitrous button was the best.
Would we have Buckner and Garcia playing over the stereo?
C’mon c’mon, do the Donkey Kong
