RPG Site did some data mining in the Steam registry files and discovered a quite surprising fact: Final Fantasy VII and VIII have been part of the Steam database for a while now, even if their release has never been announced.
Also, Square Enix seems to have done some editing on the files of the old PC ports of the two games, including the updating of a fan-made launcher that allowed higher resolutions and stretching the aspect ratio from 4:3 to 16:9.
Obviously the actual games aren’t available for download and, given that the latest update to the files dates back to early 2010, it’s hard to envision that a release will actually come.
It’s entirely possible that Square Enix attempted to improve the compatibility of the two classics, but didn’t manage to get results that would warrant a release, or simply abandoned the project for some reason.
You never know, though. The files are there, at some point there definitely was a reason for them to be there, so we might be in for a surprise, especially considering that the company stated the intention to expand the digital distribution of past titles in a recent earnings report.
