Final Fantasy 15: officially not yet confirmed for PC. Also Final Fantasy 15: shown here running on PC.
Final Fantasy 15 has never been confirmed for PC but we're all kind of expecting it to happen eventually - especially after director Hajime Tabata showed Final Fantasy 15 during Nvidia's GDC 2017 event this week.
The video above is a sizzle reel for Luminous Studio, Square Enix's in-house engine, which it won't license out but flouts on the regs in order to attract talent to its core development teams. The first half shows off work done on Final Fantasy 15 in 2016, but when the video transitions to 2017 at about the 1:50 mark, we start seeing new stuff.
This new footage is flagged to show it was captured running on the new Geforce GTX 1080 Ti. These are the "technical tests" Tabata showed off at GDC 2017, which definitely in no way confirm Final Fantasy 15 is coming to PC. Nope. Uh-uh.
For those of you hanging out hoping for a port announcement, Square Enix confirmed Nier Automata's PC release date today. This is good news as Platinum Games recently said the PC port of Nier Automata might be delayed due to concerns over the lack of secure DRM options; presumably Square Enix has now sorted that out to its satisfaction, so that's one less barrier to Final Fantasy 15's eventual PC release.
Final Fantasy 15 is already a hugely impressive game on consoles, and it'd be inetresting to see what Tabata's team could do with the extra power of modern PCs. Let's all keep hoping.
