Its much closer than you think. Slower gameplay, the goal is to use simple repeated attacks to launch or defeat enemies. The levels often have gimmicks too.

As for "simple repeated attacks", they actually have stale-move negation. Combos can actually be a bit more complex (http://www.ssbwiki.com/combo). Level "gimmicks" have been in many fighters, especially modern ones (i.e. Gods Among Us) and are hardly a new or foreign concept. You're suggesting that being faster, having tedious combos, or lacking map features would make it more of a fighter.

Soul Caliber is a difficult one to explain. Its sorta in its own genre.

So Blazblue is more of a fighter than either Smash Bros or Soul Caliber? What is this magical new genre they supposedly belong to?

Spoiler:

Soul Caliber was a tad slower, had some simpler attacks, and had map features.
