So I had some of my mom’s friends show me around Kowloon and we found two arcades. There’s on head to head at a place called Silvercord near Kowloon Park, and there two head to heads at some Namco arcade on the 6th floor of the Trade Center. I visited the Silvercord arcade early in the day, so I can’t comment on the scene. I went to the Namco arcade at around 4:30 - 5:00. There were people there playing 3S, but they weren’t so hot. I managed to beat this one Dudley player repeatedly with my crappy Hugo. I’m in mainland China at the moment, so I won’t get the chance to explore for another few days.
Also, as a side note, my friend said that I shouldn’t go to arcades late at night since people get rowdy. I supposed if you’re big and burly or have several friends, that shouldn’t be a problem, though.
