Don't feel like that, this game series is fairly underrated. :P (I didn't even know about it before this thread).
Its at tekken/soul caliber level currently.
They got a big following back in japan, but since the game isn't exactly anything but a mugen(SF or FF style game), its hard to get a following in the states.
--Even if the game is in true HD and looks ten times better than Skull-girls or that shitty Persona4Arena game.
