It wasn’t too much of a faff getting it installed but Sega locking it to NA meant that if you did want to buy anything, then it became a bit more of a headache. Hopefully the Steam release fixes that, I’ll find out later if I’ve got time this evening.
That said everything the bloke said in Ayns’ previous link is true - especially the entirely incomprehensible story, which basically you just have to ignore and embrace the grind as far as I can tell.
