Keeping the tile system used in the original game for this port. Just shows the continued utter incompetence and lack of care in Square Enix's treatment of the FF brand in re-releases of these great games.
I mean,FFS. This was ported and designed primarily for phones first. And there a billion different handsets with different display resolutions out there. How do you not figure out, that scaling at non-integer factors with images entirely designed to be aligned tile by tile are going to have seams and other crap? Why would you not spend the time and effort to do it proper and convert all the images to a correct format with layers that will scale arbitrarily without much issue? Especially when it's a new port from the ground up.
If you guys can figure out a way to make this work, (And a way to mod the terrible mobile phone UI to one closer the original game) with the Steam version.
The flood gates could be opened to producing, like FFVII, the high quality backgrounds it deserves.
I found this comparison tonight that someone uploaded to Screenshotcomparisonhttp://screenshotcomparison.com/comparison/187711
Not a bad start at all.
