$16
The cutesy, 3D Final Fantasy IVremake released on Nintendo DS in 2008, then mobile devices last year (along with a 3D remake of The After Years) has nowcome to Steamwith things like trading cards and achievements, at typical Square Enix price: $16.
I still suggest tracking down a copy of Final Fantasy IV Advance(because of the horrible, softened sprites of Final Fantasy IV: Complete Collection), but if you need 3D and voice work, here you are.
