Should fighting games include a beat em up portion?

walk to the right, punch people, punch large dude at the end, move to the next level.

i doubt it gets any more complex than that.

Sure, I mean, if you don't want the game to be fun.

dont get me wrong, i love beat em ups as much as i love shoot em ups. point is, they're simple enough to be done without problems, yet its been ages since a decent game of this genre has been develop. let alone one of the current "main" franchises have develop any real interest into them.

i'd say they have turned into what we know today as hack n slash games(to an extent) wich is not really a bad approach to the genre, but i'm pretty sure that that is not just what we most want.
