Agreed. In fact, it's really the only one that does at all IMO. There are LEAST 30 or so Final Fight games I know of made with OpenBOR, but most were made before it could properly replicate basic beat em' up mechanics. They're about as close to Final Fight as Yie Ar Kung-Fu is to Street Fighter 2.
Even Fight Forever that @Mr.Q! is working on isn't really Final Fight. It's awesome yes, but plays more like Dead or Alive or Tekken with a Final Fight theme.
