Hyper Dimension was a good DBZ fighting game... I wouldn't mind seeing a port of that, if it were actually possible.

Anyway, I've heard Legacy of Goku compared to Legend of the Super Saiyan for the Super Famicom. I tried that for a bit. Looks a little weird in the graphics department, but it seemed interesting enough. Battles involved cards.

I don't expect that will be the case with LoG, though.
