I would get dropped off with a friend at the mall at 7am with $10 each in our pockets and would get picked up around 9pm later that night. That $10 had to be used wisely between Sbarro, the arcade and soda throughout the day.
Looking back, it was pretty trusting of my parents to let a couple of young teens spend all day at a mall but it felt perfectly safe and I have zero memories of any issues. I still remember spending roughly $5 for food and then changing out the other $5 for quarters. That feeling of having $5 whole dollars of quarters in your pocket was awesome. Then, you had to careful choose your games to last all day.
Once the Saturn and then the Dreamcast came out, that really felt like the end of arcades. You no longer got watered down ports of arcade games and there was no reason to go anymore. When MAME came out, I finally got to play and beat every single game I wanted to play but didn't want to waste quarters on back in the day. It was amazing finally getting to play the actual arcade version of games when you had to settle for 16-bit ports of those games for the longest. Games like Street Fighter 2 were good on the SNES but it never really scratched the itch for me and I'd still play it in the arcade when I got a chance. MAME finally ended all of that.
Now, I have a Arcade Legends Ultimate cabinet in my media room. It's not perfect but it's still a friggin arcade cabinet and has virtually every arcade game ever made on it (via USB drive). Never in a million years as a kid I thought I would have an arcade cabinet much less the concept that it would have every game that ever existed on it.
