It’s probably been mentioned by someone else, but I’ve also got the Jap version for the amazing Dreamcast! (yes, that’s right! I said amazing, what a console that was! Not a day goes by when I think about it!), anyway, it is a great game however REAL hard, but is also very rewarding as you progress, its really original and since its available on the Gamecube, that cant be a bad thing, can it?
But nothing beets the playability with the “’Official’ Dreamcast Arcade Stick!” on the good old Dreamcast!
