Hmm, that is a drag but on the other hand it's only six bucks and I've always heard people rave about the game and the series. I've never played a Final Fantasy game myself.
Buy a license in the sale then play the PS1 version in an emulator.
This is what i did: bought it, downloaded the game, installed it an then used Tifa's Bootleg. It converts the game to the old release, so cloud saving and DRM are gone (yay!), but CD check is still there. http://forums.qhimm.com/index.php?topic=13212.0
More than 20GB of mods. HD models (battle models outside of battles is one of the main reasons this version is better than the PSX one), HD textures, damage and HP and MP limit break, save anywhere (and various cheats), more soundtracks, improved menus and fonts, etc.
PS: you'll have to get dummy ISOs or rename an HDD/USB drive, so the game thinks the CD is in the drive.
