I don't really have time to go through a whole 53 minute video of the game, nor am I super interested to since most of it is just stuff that's in the early parts of the game anyway. I'll say that they have some balls putting out a video like that because for better or for worse, they're showing people what to expect from the game as it is.
So... the good? I think that coming off FFXIII being a divisive disaster, especially with two sequels which performed subsequently worse and worse, and FFXIV being a MMORPG which doesn't fill the needs of single player FF fans, FFXV feels about as inoffensive as it can get in the modern gaming climate. I think this is an important point in recapturing good will from the mainstream market, especially internationally, but it also makes the game feel really boring. By inoffensive I mean it seems to check the bare minimum in every checkbox for what people expect from a modern AAA console RPG these days. But that also makes it feel like it lacks a unique aura of being a major new FF title rather than a FF title trying to be everything else which is already popular. Oh well.
The art design is top notch though. I think visually the game looks interesting, the monsters look great, and while the world looks kinda plain, there are FF elements which give it a unique flair. The same can't be said about the graphics, which well... honestly... look like a prettied up PS3 game. I don't think that's an exaggerated statement either. The animations, the textures, the lighting, the open world-ness, etc, there's nothing there which really screams like it's a leap from GTAV for example, which was a PS3 game. Compared with other native PS4 titles, there really isn't a comparison at all. In particular the animations look janky as fuck. Probably the most disappointing part.
Story-wise the video makes it very clear that the game is going for a straightforward and traditional tale which puts its cards on the table early and you're following a fixed collect em all journey which links you from point to point. I don't think that's bad as long as each location is interesting and has smaller stories of their own. We'll see. But overall, what the video really reminds me of is that FFXV really seems to want to be... a brand new generation's FF1. It's an odd feeling but that's what I see. Noctis and his three friends are the four Warriors of Light. They go on a journey to seek out macguffins, to defeat some great evil being and save the land, and the mission motivation is driven by a single princess. FF has attempted many different stories since FF1, but since the first game there hasn't been one with such a simple set up. Ever since they have started telling large scale stories, FF has been about unwilling heroes or quests driven by deception. This seems to reset everything right back to a group of adventures with a common purpose who know and trust each other before the game even began, going on a quest with specific objectives. We'll see how that pans out.
