Street Fighter Alpha 3 World Tour Mode is the only mode of a fighting game I played extensively. (Not counting Smash Bros Melee).
Despite lacking the great artstyle of SF3, the world tour mode was a lot of fun and pretty varied.
Personally though, and I say this as a casual of the genre, I don't think they should try to appeal to our crowd in the first place.
Edit: oh I just remembered about Soul Calibur.
Played a lot of that too (1 &3 especially) in the campaign mode the had.
