The premise of this thread is simple but very helpful: post in this thread the best or just any good japanese exclusive games for classic systems. Here in the west we missed out on some kick-ass titles and here we should compile all of the japanese only titles we love for classic systems (classic meaning pre-PS2). Improved ports are acceptable (same game title but changes in the Japanese version). This will provide a larger database with all of our favorites!
I can already think of Kid Dracula and Splatterhouse: Wanpaku Graffiti for the Famicom that never made it to North America.
