Don't talk about "the big head start"
Installed PS2 user base in Japan: About 6 million......divide 669,323 into 6 million, and you get 1 game for every 9 systems or so
As for RE...
Gamecube's user base is about 1.5 million in Japan.....divide 104,000 into that and you get 1 game for every 15 systems...
Whether it's a remake or not, it got a 39 out of 40 from Famitsu...and should be selling better than it is...
