Should fighting games include a beat em up portion?

[Omegajak]

Would the adventure mode in Tobal No.1 or Ehrgeiz count as a beat-em-up? Or is there some criteria that they must have to count?

Did everyone just kinda miss this post?

Fighting game roots are in Beat em ups. Creating a Hybrid shouldn't be difficult. Half down the options in a fighter and you have yourself the core of your beat em up.
