Before I talk about the game as the interactive artwork it is, huge disclaimer: Final Fantasy 15 Windows Edition is a very resource intensive game, even four years after its launch, and especially on higher settings with optional NVIDIA hair/environment enhancements enabled. I have a system that exceeds the recommended specifications but still experienced slowdown in a handful of areas in the overworld, one of the mid-boss fights in Chapter 14 of the game, and a handful of significant story cutscenes. In two instances the game froze up and required a restart. In two other instances, the game crashed outright. In a handful of other instances, I had to save and reload to return to a stable 60 FPS. *There was even one instance where I had to restart my computer entirely.* There were also issues with sidequest NPCs not spawning when they were supposed to, which had to be fixed by saving and reloading. Most of these issues occurred after the 40 hour point in the game for me, so if you're having any trouble maintaining at least a capped 30 FPS at the start of the game, please consider refunding it before the Steam refund window runs out -- the game only seems to get more resource intensive the farther you are in the story. If you do decide to keep playing, save frequently: autosave is great, but it doesn't autosave as frequently as one might hope, and in one instance a crash caused me to lose a little over an hour's worth of sidequesting.

All of that aside, the game is a lot of fun, and the 80 hours of playtime I put into it felt worthwhile. I was skeptical of an all-male roster of main party members, but honestly, road tripping with the boys was a delight and there were a lot of great moments with plenty of other characters, too.
I found the story quite compelling as far as Final Fantasy plots go, and was surprised to learn partway through my playthrough that the Windows Edition automatically comes with the Royal DLC, which adds additional sidequests to the game and expands the story's final area as a result.
Gameplay is also quite good, and a step up from FF13 imo. I played on normal mode with the wait timer enabled (combat freezes when the player stops moving and causes the wait timer to start ticking down; combat can no longer be frozen during the encounter when the wait timer runs out) and found the difficulty was just right for me. I also found it rewarding to encounter and run from megafauna in the overworld that I later came back to fell, and I enjoyed being able to upgrade the party's car to be able to run over enemies in the road and ward off daemons, as well as go off-road.
FF15 is a great action RPG, and totally worth giving a try so long as you're confident your computer can handle it!

(POST-GAME OPINIONS: I originally wrote the above review after completing Chapter 14, which concludes the game's main story. When the credits roll it will ask you to choose a save file through which you will load the post-game, which is contained in Chapter 15. You *must* choose a manual save file, not an auto save file. I failed to do this correctly and had to fight the final boss again to rectify it.
Upon loading Chapter 15, I was given a message saying 'some game functions would be unavailable in the post-game and hunts would be reset.' With hunts reset, you're back to being a level one hunter. I spent tens of hours getting up to Rank 4 hunting prior to completing Chapter 14 and now I have to do that all over again to take on higher rank hunts. Theoretically, if I had a manual save where I was still in Chapter 14, I could go back and finish all of my hunting before finishing the main story... but I overwrote my only manual save slot with the Chapter 15 save because the message about hunts being reset doesn't come up until you load Chapter 15 via the chapter select. While resetting hunts allows the player to gain all of the rewards from these hunts again, it means you're going to have to redo a lot of hunts to get back up to the level you were at. Personally, I would rather be able to continue with my hunting rank intact so I can just do the hunts I haven't completed yet -- I don't need the gil or extra accessories/items gained from completing the hunts again.
Chapter 15 also resets a ton of sidequests. On one hand, it means easy sources of getting more experience, but it's also super annoying being level 70-something and then being given level 6 quests I've already done before. As for the game functions that are unavailable, it seems like the off-road Regalia is gone, but the game allows you to convert it into a combination car/airship instead. You have to re-clear one of the imperial bases to get the part you need, and it kind of seems like other imperial bases are also reset -- if you've done the Final Fantasy 14 tie-in sidequest, that one resets for sure. Anyway, about the flying Regalia: immediately after converting the Regalia to its airship form, I drove away from Cindy's shop without even flying and the game crashed.
I think I might be giving up on the post-game and sticking with my fond memories of Chapters 1 through 14. I might revisit FF15 for the character-specific DLC eventually, but the main game's post-game has lost its luster now that I know how much in the world has been reset and then immediately crashed in an area where I've never had performance issues before. Sure, there are new quests, but the whole map is undiscovered and all of the fast travel points you've unlocked are gone, so even though you keep your levels, items, equipment and Regalia upgrades, in a lot of ways it feels like you're back to square one.)
