Okay, so we're starting to get just about every main-line Final Fantasy title on the PC platform. They haven't always arrived in good condition, with Final Fantasy XIII having major user interface issues, which were mostly (but not entirely) patched, and Final Fantasy IX requiring the installation of a few Android plug-ins… on Windows. Still, many of them are classics and it's therefore good to have them on platforms that (barring current UWP discussions) encourage perpetual compatibility.
As for its system requirements? They don't specify integrated GPUs, ie: Intel, but what they do list are what we would expect for a game that targets the Xbox 360 and PS3. If it comes from AMD or NVIDIA, and they are still releasing drivers for it, you should be fine. SquareEnix declares a minimum of either a AMD Radeon HD 2600XT or a NVIDIA GeForce 9600GT.
Excluding the spin-offs, the PC is now missing just the original Final Fantasy, Final Fantasy II, Final Fantasy XII, and the upcoming Final Fantasy XV. The rest have arrived on the PC in some form, be it a port of the original or one of their remasters. Still no word on any of those remaining four, though, but it seems like Square is just dropping games onto Steam with a few days of notice now.
Oddly enough, no price is listed (at least in Canada). No idea why.
