I don't think "not for sale" is correct, since you can
definitely buy this thing (standalone or not doesn't matter); you pay a higher than usual price and get a game too (the shoe being on the other foot).
It's not me not liking "Resident Evil" or not knowing it has been the western title. I'm just asking if that's the official title (on the webpage, or in the tags), or the submitter just preferred it.
In the
Steam store the price is 39,99€ and they mention a 13-track bonus soundtrack, that's probably it.
