I spent a lot of time in the arcades with SF2. Lot of quarters too. Same with Street Fighter 3 when I was in college. I think I actually broke the joystick on the machine from playing it too much. (Other than SF2, it's the only arcade game that I ever really tried to completely defeat.) Now I enjoy them on my home consoles and on some ROMS that I play on my computer.
Having said that, I don't know about kids and arcades these days. (Gosh, I just sounded old.) When I can FIND an arcade, I find that most of the games are either crane games, first person shooters, or snowboard/4-wheeler/racing car sims. There are relatively few "fighters" out there anymore. The last time I went into an actual arcade (not just a movie theater lobby), I had to go all the way to the very back to find Tekken or Soul Calibur. I had to wade through about fifty different versions of Time Crisis, the new Area 51, the new Silent Scope (which is actually a great game) and on past the air hockey tables.
And it's also true that it's getting harder and harder to find an arcade anymore.
