I have both of these games. Love the original on the Saturn. A great plus was the Christmas NiGHTS. Played this game a lot. Logged in many hours. Finished that game over and over and over again.
Somehow I never got into the Wii NiGHTS. It might be because I never quite got into the Wii that much. The controller was just difficult to accept. Maybe I need to take another look at this game. Need to pull it out and play it again.
