Yeah, this game does look a little dated now, particularly next to screen shots of the upcoming XBox incarnation, but then so does every game from the mid nineties...
However, despite John D's continued negativity (do you even appreciate classic gaming?), this game series is one of the major highlights for the Saturn, Zwei being no exception. The controls were nice (esp. with the 3D pad), the graphics were highly atmospheric, as was the sound. And that, in my opinion, is the high point for PDZ... atmosphere, which - for a shooter - it has tons of.
I remember the rush of zooming through caverns and having my dragon morph into different forms depending on how well I did... great fun, and worthwhile for anyone who likes the idea of a shooter with depth.
