Done with Fatal Frame III. This was another very strong entry with a few strengths but also weaknesses over II. Overall I'd rate them very evenly, maybe preferring one title over the other based on the phase of the moon.
The strengths are increased difficulty and thus tension, some qol (switching film on the go, though oddly not lenses?), very clever ways to screw with the player and keeping the experience fresh with new tricks.
The weaknesses are the controls and padding. I complained about the controls earlier, and I think they're strictly inferior compared to how they were in the previous game for no good reason. I also think they could've cut 20% of the game by not repeating some fights so many times. Some ghosts are repeated to a good effect, like how the crawling woman is teased towards the end multiple times but I never actually fought her again. Presumably I would have had to seek her out, but at this point the game had already introduced a new mechanic that forces you to keep up a pace. If you loiter around too long, the game will throw stronger ghosts at you, notably the unbeatable tattooed woman has a high chance of appearing. So there's a bit of a conflict of interests here. The game is padded out with the same ghosts being fought multiple times. It expects you to do this for a good rank. It also punishes you for taking your time and exploring more by putting you on a timer. And I think for a first playthrough, trying to play 'optimally' by seeking out all the ghosts multiple times would just make for a worse experience, over just being immersed and going with the flow. Here I'd say above all else completely disregard whatever rank you think the game might give you on your first playthrough, save that for later.
Another ghost I was mixed on was the long haired woman. She only ever hangs out in her own room and her third encounter is really good. The introduction subverts your expectations regarding game mechanics and then she totally switches her moveset. It makes for a really memorable encounter and you think that was a good way to send her off... until you fight her a fourth, fifth and sixth time. Ya blew it, devs. The shrine maiden girls suffer a similar fate in that since there are multiple of them, you'll be fighting them so many times it becomes silly. First one at a time, then two, and eventually all at once, more than once. They do at least switch their moveset, but you'd still better watch your feet.
Some ghosts get special treatment where rather than being able to be fought at regular intervals, they seem to switch roles and instead get a chance to appear in random places. At least, that is the impression I got. One such case is the plane crash woman, who has a neat arc in how she starts haunting you. Eventually you'll meet her way outside her room and once I managed to encounter both her and the tattooed woman in the same room, which was a real 'nope' moment and I proceeded to promptly fuck off.
Now, the ways the game screws with the player. This game does a great job in setting up expectations and then subverting them, and it displays considerable restraint in not repeating its tricks. Particularly in your house, you expect things to sound a certain way, for certain camera angles to be there and so on. When something's off, you can immediately tell and want to investigate. The house goes from being a place of comfort to "oh boy I wonder what's going to be off this time", but things may actually be completely normal. Another neat twist is how the game ties into 2, it's a real treat. I'd say you will at the very least want to have played 2 before this game, and also the first game if possible, though I hadn't.
In some ways, this game drags on both more and less than 2 did. The main culprit are the aforementioned repeated ghosts fights. What helps the game stay fresh is with three playable characters with different abilities. The main girl Rei and the dude Kei are the most similar, mainly differing in their loadouts of healing items and film but also in the order of the lenses they unlock. Kei also has the most undercooked stealth mechanic in the history of video games that you may as well completely ignore as running is a more valid tactic. The first game's protagonist Miku differs the most mechanically as she doesn't use lenses rather she has her innate ability to slow down time and charge up shots.
Now, I was thinking of giving 5 a fair chance. I don't expect it to be nearly as good as these two, but I'm the kind of guy to find out for myself.
Edit: about the HD pack and undub. In 2 the undub worked great as practically everything was subbed as well, but in 3 there is a lot of incidental unsubbed dialogue that you won't understand with the undub. So if that bothers you, maybe try out the dub first. The HD pack was quality as always despite being unfinished and the game looks fantastic for its age and considering it's being emulated.
