A lot of the appeal of arcades back in the day was the obvious graphical difference between home consoles and the arcade experience. It seems once that difference was blurred, the arcades seemed to disappear. In what way could companies such as Sega differentiate their arcade models from the home consoles, to bring about even a muted profitable return to the past experience? I don't know about anybody else, but I truly miss having local arcade parlors I used to frequent as a kid.
