Monsters of the Deep: Final Fantasy XV takes the fishing component from the main Final Fantasy XV game expanding on it and turning it into a standalone game in VR. This game as of this review (1/2023) is ONLY available on the PSVR. It's a fun, interesting, albeit frustrating experience that is mostly held back by the technology. For the main story quest line, you travel to different fishing holes, usually being accompanied by one of the characters from FFXV as you are trying to rid that spot of the demon/monster fish. This is done by catching enough of the standard fish in the pond until you fill a specific meter. At that point, the monster fish will appear and the game turns into a shooter style game with some light puzzles to damage the fish. After causing enough damage, you go back to your fishing rod to try and reel the fish in. That is the entirety of the main story missions, with some extra side content thrown in such as specific "monster fish" style "hunts" where you may need to use a specific type of bait and the fish is harder to catch than the normal fish. Other modes include some tournaments both online (though I'd imagine dead at this point) or offline, as well as a more relaxing traditional fishing experience with no monsters or objectives. I didn't realize you could play this game using a dualshock controller, though that removes the immersion of the vr. What also ruined some of the immersion of the vr is the playstation move controllers. To play this the "proper" way, you need to use the move controllers that are based off the playstation 3 move system. These controllers were never great to begin with, and that still remains true even using them on the newer generation hardware. Many times you can make the same exact casting motion and the lure could either land 5 feet in front of you, or yeet the lure to where you can't even see where it lands. This makes it frustrating as it ruins immersion and introduces frustration while repeatedly casting trying to figure out exactly what the game is expecting of you. There is also some pretty cringey Cindy fan service in the game. Cindy is a mechanic you meet in the main FFXV game who fixes up your car very early on and is wearing the daisy-est of dukes with her coat barely zipped up and very generous genes hanging out. In this game, she will randomly come over to your house/cabin to fix up your car (even though nothing happens to it?). When you go to start the next mission, you'll start in your car and she's bent WAY over looking away from you, then she'll realize you "are leaving already" then lean WAY over looking your way. Not to be a prude, but this was unnecessary and gratuitous. I did still have fun with this game, never knowing what wild thing would happen next. If you can find it on sale, I would definitely recommend it as long as you already have the hardware required for it. It's certainly not worth picking up the hardware just for this game.
