Legend of Grimrock 2 is 5.99 on GOG.com today FYI
There is an awesome mod that really improves Planescape to a more modern state (resolution, etc.) Made it much more enjoyable when I replayed it last year.

The later FF games suffer in story, but make up with visuals. Some of the best artwork I've seen to date.
Quite a list, enjoy!
