Couple stand out to me:
- 
Seeing Virtua Fighter for the first time back in what 1993 or so at an amusement park and being wowed by the graphics, thinking it was photo realistic. 
- 
Seeing Mortal Kombat 2 on a big screen CRT cabinet and thinking I was going to go to hell because of the violence (lol). 
- 
Playing X-Men with my dad and his friend and his kid on a 6 player machine that had widescreen, very cool for the time. 
- 
Pumping endless quarters into Aliens vs Predator (one of my favorite arcade games). 
- 
Seeing some dude beat Tekken Tag which I could never clear and thinking he was the coolest. 
Arcades were great. A dream of mine is to visit a game center in Japan and play some of the classics on an actual machine.


I remember seeing the intro to Super Street Fighter 2 with Ryu bobbing up and down then doing a hadoken and being wowed by the effects.
