Arcade machines would only keep the high score until the machine was powered down, and if anything it would accept no more than 3 letters. I can assure you when cartridge games started saving progress ( Legend of Zelda on NES ) That was magic. Still long after that arcade games still never saved all time records.
In the early 90's I remember when Street Fighter II hit the arcades. It was the best game I ever played. From the time I got home, I was like....Wait... I must play that game again. Then the next time I saw it, it there was a huge crowd waiting to play. The spectators would cheer at the rounds, some arcades bumped it up to 50c per credit and us youth would blow away a lot of money on this over time.
At the time the SNES was on the market, and gaming hype was done through magazines. When the magazine showed SFII for the SNES, it was a miracle. No game on the home console was this damn close to the arcade, and on it's release it did not disappoint.
For me the last great Arcade Game was "Killer Instinct" An arcade game that was suppose to display the power of the upcoming N64. In short the N64 wasn't powerful enough to handle Killer Instinct which is funny, cause the arcade ROM still has an announcement with a logo in the beginning saying something like, coming 1995 on Ultra64.
In malls Arcades were clean and packed with youths with some guy in a dealer uniform with a pouch of coins while the arcades downtown were packed with youths but it had a more urban grimy feel to it, and the exchange guy would be behind a glass. If you were a student there was always that vibe that you should not be at the arcade.
