One of the first titles I played back in 96 when I finally got my hands on a PS. I didn't know too much about shooters back then but, I remember playing Raiden in the Arcade and on Atari Jaguar.
I could tell from the first couple tries that there was something magical about Raiden Project. Maybe it was all the kewl explosions I had never seen possible in the comfort of my own home. Plus the humongous ray waves you could build up during the game. That was the first time I realized that the PS was capable of reproducing Arcade quality shooters. In the Hunt, was awesome that summer too.
Yes, the re-mixed music is wicked also. I also like the Intro music with the 3-D version of the ship flying around.
