Don't you think some arcade games should have controller ports?

[Zclyh3]

I mean, some people don't like to use the arcade joystick. Wouldn't it be cool if the arcade offers some type of control insertion? I mean like a DC or PS2 or XBOX or Gamecube controller port? OR even better yet, Namco can make money by selling their own controllers so people can use that instead of using that hard ass joystick. IF they had this type of option for Soul Calibur 2, I would would whoop so much ass.
