I'm pretty sure I made a good choice then. The local stores tend to just slap a 50€ price tag to anything they see.
EDIT: Oh, I just realised a cool thing yesterday. I bought RE3 a couple weeks ago (I know, I've been missing out), and on one of the streets there was a cinema. In front of the cinema there was a poster for, apparently a movie, "Biohazard 4". Now that I saw it again, I realised the '4' in the poster is the exact same 4 as in the Wii RE4 front cover. And the Wii edition, as far as I know, is the one called 'Biohazard'.
IT MUST BE FATE~
