The imported variants of Hostel and Vacancy are available locally. Hostel was released a few years back and could be seen in a marked down price (I think it's part of the ongoing Php 895 50% Off Sale of Magna). The imported variant of Vacancy was released in the last quarter of 2007 and was among the first titles to have the introductory price of Php 695. I think there aren't too many copies of this released, as not all stores have them, and in stores where they are available, only a handful are in stock. The local variant (Php 475) is part of the 50% Off Sale, but not the imported one.
I have yet to see an imported variant of Hostel II.
