my first arcade i can remember was street fighter. i was like 3 or 4. i didnt even know what it was. i was like wtf. i remember wanted to get blanka cuz he was green but i didnt know better and got chun li. then i was crying and uber pissed because there was no jump button and i didnt know i had to press up to jump...
but my favorite arcade games were:
ninja turtles II (the one where they fight in the hotel thats on fire)
that 4 - 6 player xmen game ( i remember fighting the blob and pyro)
street fighter games.
